[Sato Residence — March 30th, 1:47 AM]
Beneath her duvet, the girl's hand drifted unconsciously to her lower abdomen—and the moment her knuckles grazed that patch of skin, her thighs clamped together on pure reflex.
What... what is this...?
Ruri's face burned in the darkness, pupils blown wide with a haze she couldn't name. The signature Fuyumi had scrawled across her belly—just above the waistband of her pajama shorts—pulsed with phantom warmth. Heat radiated from the spot like someone had pressed a fresh brand there, spreading through her pelvis in slow, rolling waves.
She'd felt strange ever since she got home. Restless. Sensitive.
But this—lying in bed with her heart hammering against her ribs, her skin prickling with awareness—this was something else entirely.
It's like... this afternoon... Her mind flashed back to his bedroom. His fingers on her chin. His mouth against hers. The way he'd pushed her down against the mattress and kissed her until she couldn't breathe—
"Nnh—" A tiny whimper escaped her throat before she could stop it.
Her hand pressed flat against her stomach. The heat concentrated there was maddening—an itch that burrowed deeper the more she acknowledged it. Without conscious thought, she began rubbing slow circles over the signed area, and the friction made her spine arch involuntarily.
This is wrong. This is so wrong. I shouldn't be—
But her body wasn't listening anymore.
The signature throbbed beneath her palm like a second heartbeat. Every brush of her fingers sent sparks cascading down through her belly, pooling between her legs in a way that made her squeeze her thighs together tighter.
"Hahh... haah..."
Ruri's breathing grew ragged. Her free hand fisted in the sheets, knuckles white, while the other continued its shameful exploration. The thin cotton of her pajama top had ridden up to her ribs. She could feel goosebumps erupting across her exposed midriff, feel her nipples hardening to stiff peaks beneath the fabric.
The pleasure was unlike anything she'd experienced before—syrupy and slow, building in intensity with each stroke over that damned signature. Her brain kept conjuring images without her permission: Fuyumi's dark eyes looking down at her with that predatory gleam; his lips curved in that infuriating smirk; his breath hot against her neck—
"Mm... mmn...!"
She was rubbing harder now, palm grinding against her lower belly in desperate circles. Her hips had started moving on their own, rolling up to meet her hand with a rhythm that felt instinctive and primal.
Why can't I stop? Why does this feel so—
"Hah... ahh... F-Fuyumi..."
His name slipped out without permission, breathy and wanting. The sound of her own voice saying it—needy, desperate—sent a fresh wave of heat crashing through her system.
Her hand slipped lower.
Past her navel. Past the elastic waistband of her shorts. Into unfamiliar territory.
The first brush of her fingertips against damp cotton made her freeze. She was wet—soaking through her panties, actually—and the realization hit her like ice water and gasoline at once. Shame and arousal tangled together into something overwhelming.
I can't... I shouldn't...
But her fingers were already moving, tracing the outline of her slit through the thin fabric. The indirect contact sent bolts of electricity up her spine.
"Nnh—! Nnnnhh...!"
Ruri's body curled in on itself beneath the covers. Her hand pressed between her thighs, fingertips finding that swollen little nub at the apex of her sex. One touch, two—she rubbed in tight, frantic circles, hips bucking into her palm with increasing desperation.
Her mind blanked. The heat that had been building in her core suddenly crested, shattering outward through her entire body in waves.
"Ah—! Ahhhn—!"
She came with a muffled cry, spine arching, toes curling, thighs clamping tight around her own hand. Pleasure crashed through her like a tsunami—bright and white-hot and all-consuming.
When it finally subsided, Ruri lay boneless and panting beneath her duvet. Her chest heaved with each breath. Her face was burning. And between her legs, her fingers were coated in something slick and warm.
I just... I actually...
The realization of what she'd done—what she'd done while thinking about him—crashed over her like a bucket of cold shame.
Her panties were ruined. Completely soaked through.
Ruri stared at the ceiling in the darkness, lips parted and trembling, wondering how in the world she was supposed to look at Fuyumi Sasaki tomorrow without spontaneously combusting.

[Sasaki Residence — 12:01 AM]
> DAILY SCUM EVALUATION
>
> Performance Rating: Outstanding
>
> Scum Points Awarded: +200
>
> Current Balance: 200 SP
>
> Assessment: A scumbag taking his first steps. Promising, but unremarkable.
Fuyumi stared at the holographic notification hovering in his peripheral vision.
Two hundred points. Not bad for a first real attempt—but hardly impressive either. He'd only worked on one target today, and while Ruri had provided excellent material, the system clearly expected more variety.
Should've known Rei wasn't coming.
He'd waited until nearly eleven PM, but the mature woman never showed. Disappointing, considering how flustered she'd been when Ruri left his apartment. He'd assumed guilt—or maybe jealousy—would drive her to knock on his door for "clarification."
Apparently not.
Can't pursue her directly though. That would break character.
The persona he'd cultivated—harmless, sincere, slightly naive—required her to come to him. Any aggressive pursuit would shatter the illusion and send her running.
Nothing to do but wait for tomorrow.

[Sasaki Residence — 8:23 AM]
Fuyumi woke to sunlight streaming through his curtains and a new system notification blinking insistently in his vision.
> MOOD DETECTED: Irritation (Minor)
>
> CAUSE: Target [Yuki Rei] failed to appear yesterday as anticipated.
>
> INITIATING: Revenge Quest
>
> OBJECTIVE: Make target regret her negligence.
>
> ROUTE OPTIONS:
The notification expanded into two distinct pathways.
> ROUTE A — Psychological Manipulation
>
> Wait for target to approach. Deliver an Oscar-worthy performance of emotional distress. Claim the following: Your crush visited yesterday. You confessed to each other. You kissed, touched, escalated toward intimacy. But when she reached for your lower body—you couldn't get hard.
>
> The reason? After your intimate contact with Yuki Rei, your body no longer responds to youthful, immature figures. Only mature, womanly curves can arouse you now.
>
> Estimated Yield: 300-500 SP (Variable based on performance)
> ROUTE B — Aggressive Domination
>
> Enter target's home uninvited. Proceed to her private room while Tanaka watches. Lock the door behind you. Proceed to train her while her fiancé listens from the hallway.
>
> Estimated Yield: 800-1200 SP (High risk, high reward)
Fuyumi's lips twitched.
This system really is something else.
Route B was tempting from a pure point-efficiency standpoint—but far too reckless. Rei would call the police the moment Fuyumi forced his way in, and no amount of Scum Points were worth a criminal record.
Route A, though...
Route A was elegant. It played directly into Rei's existing insecurities—her fading youth, her cuckold fiancé, her desperate need to feel desirable. The claim that a young man found her more attractive than his teenage crush? That would burrow into her psyche like a parasite.
> ROUTE A SELECTED
>
> Objective Updated: Convince target of your "affliction." Make her feel responsible.
Time to prepare.
Fuyumi climbed out of bed and padded toward the bathroom. His reflection in the mirror showed the faint shadow of stubble darkening his jaw—good, that would help with the disheveled look.
He left the stubble unshaved. Ran his fingers through his hair until it stuck up in artful disarray. Added some slight bags under his eyes by rubbing them irritably.
Needs more.
He remembered the onion Ruri had bought yesterday—still sitting in his refrigerator.
Ten minutes later, Fuyumi stood in his kitchen surrounded by pungent onion fumes, tears streaming down his cheeks. The volatile compounds had done their work beautifully; his eyes were red-rimmed and puffy, his nose slightly runny.
Perfect.
Come on, Rei. I've been waiting all morning.

[Sasaki Residence —11:52 AM]
The doorbell chimed.
Fuyumi allowed himself a small, victorious smile before schooling his features into an expression of profound melancholy. He shuffled toward the door with slumped shoulders and downcast eyes.
Showtime.
He pulled the door open.
Yuki Rei stood in the hallway, wearing a simple cream-colored sweater that hugged her curves and a knee-length skirt that showed off her legs. She held a thermal container in both hands—presumably containing lunch—and her expression shifted from polite smile to genuine concern the moment she saw his face.
"Fuyumi-kun—" Her eyes widened. "Your face—you look terrible! Are you sick? Did something happen?"
Behind her, a door creaked. Fuyumi caught a glimpse of Tanaka's eye through the narrow gap—watching, always watching.
Perfect.
"I'm fine," Fuyumi said, forcing a wan smile. "Just... didn't sleep well."
Rei's brow furrowed. She stepped closer, the scent of her perfume—vanilla and something floral—drifting toward him. "Your eyes are all red... Fuyumi-kun, have you been crying?"
"I—" He shook his head. "It's nothing, Rei-san. Did you need something?"
"I made lunch." She lifted the thermal container. "I thought, since you're living alone... you probably aren't eating properly."
The care in her voice was genuine—motherly, almost, though Fuyumi suspected her motivations were far more complicated than simple neighborly concern.
"That's... you didn't have to." He stepped aside. "Please, come in."
Rei hesitated for just a moment—a glance backward toward her own apartment, toward Tanaka's watchful eye—before stepping over the threshold.
Fuyumi closed the door behind her.
The click of the latch sounded louder than it should have.
"Fuyumi-kun." Rei set the container on his kitchen counter, then turned to face him fully. Her eyes roamed over his disheveled appearance—the stubble, the messy hair, the reddened eyes. "Something happened. I can tell. Won't you talk to me about it?"
Fuyumi looked away. "It's nothing. Really."
"It's not nothing." Her voice softened. "We're... we're partners now, aren't we? You've helped me so much these past few days. If something's wrong—if you're hurting—I want to help."
She's practically begging me to manipulate her.
The irony wasn't lost on Fuyumi.
He let out a long, shuddering breath. His shoulders slumped further.
"It's about... that girl," he said quietly. "The one who was here yesterday."
Rei's expression flickered—recognition, followed by something that might have been jealousy, quickly suppressed. "Your... the one you mentioned? The girl you've had feelings for?"
"Ruri." He nodded. "She came over yesterday, after you left."
"I saw her leaving." Rei's tone was carefully neutral. "You two seemed... close."
"We confessed to each other."
The words hung in the air between them.
Rei blinked. "That's... that's wonderful, Fuyumi-kun! You've liked her for so long—"
"It's not wonderful." His voice cracked, perfectly timed. "It's the opposite of wonderful."
"What? Why?" Genuine confusion now. "If you both feel the same way—"
"We kissed." Fuyumi stared at the floor. "After we confessed... I was so happy. I'd wanted to do that for so long. And she kissed me back—really kissed me. We couldn't keep our hands off each other."
Rei's cheeks colored. This was... intimate information. The kind of thing she probably shouldn't be hearing from her teenage neighbor.
But she didn't stop him.
"We were on the couch," Fuyumi continued, his voice dropping to barely above a whisper. "Touching each other. She was lying underneath me, and I was kissing her neck, and her hands were everywhere, and I thought—I thought this was finally it. The moment I'd been waiting for since middle school."
"Fuyumi-kun..." Rei's voice was strained. "Maybe you shouldn't—"
"Her hand went lower." He cut her off, lost in his "memory." "Past my waist. She was reaching for my..."
He trailed off meaningfully.
Rei's face was now bright red. She understood what he was implying.
"And that's when I realized something was wrong." Fuyumi's voice went hollow. Empty. "Something was very, very wrong."
He finally looked up—met her eyes with an expression of profound confusion and shame.
"I wasn't hard."
The admission landed like a bomb in the quiet apartment.
"I..." Rei's mouth opened and closed. "That's... that can happen, Fuyumi-kun. Nerves, anxiety—"
"It wasn't nerves." He shook his head. "I was aroused—mentally, emotionally, completely. I wanted her more than anything. But my body just... wouldn't respond."
"That still doesn't—"
"I know why it happened." His jaw clenched. "I figured it out last night, lying awake, trying to understand what was wrong with me."
Rei went very still.
"It's because of you, Rei-san."
The words hit her like a physical blow.
"What?" Her voice came out strangled. "What are you—"
"After what happened between us." Fuyumi stepped closer—not threatening, but earnest, desperate. "When you held me against your chest. When I felt your body against mine. When I... when I touched you."
His hand rose unconsciously toward her, then dropped.
"Something changed in me. I don't know how to explain it. But after feeling a woman's body—a real woman, mature and soft and..." He swallowed hard. "Ruri felt like... like nothing. Like a child. Her body didn't do anything for me anymore."
Rei was trembling.
"That's not—you can't blame that on—"
"I'm not blaming you." His eyes were earnest, pleading. "I'm just... I don't know what to do, Rei-san. The girl I've loved for years was right there in my arms, offering herself to me, and I couldn't..."
He let out a broken laugh.
"She left crying. She thought it was her fault—that she wasn't attractive enough. I couldn't tell her the truth. How could I tell her that she's not the problem—that I've been ruined for normal girls because my neighbor let me touch her breasts?"
The accusation—gentle, anguished, utterly manipulative—hung between them.
Rei's composure cracked.
"Fuyumi-kun, I—" Her voice wavered. "I didn't mean for... I wasn't trying to..."
"I know." He reached out, took her hand in both of his. His thumbs traced circles over her knuckles. "You were just being kind to me. Helping me. You didn't know this would happen."
Her hand was shaking in his grip.
"But now I don't know what to do." His voice dropped lower. Intimate. Desperate. "Every time I close my eyes, I see you. Feel you. Smell you. And I can't—I can't get interested in anyone else. Girls my own age feel like... like cardboard cutouts. Flat. Empty. Unappealing."
His grip tightened.
"What am I supposed to do, Rei-san?"
The question wasn't really a question. It was a trap—baited with guilt and loaded with implication.
Rei stared at him, lips parted, eyes glistening with something between horror and fascination.
She had no answer.
And Fuyumi knew—watching the emotions war across her beautiful face—that Route A was already working perfectly.
