Chapter 12: The Perfect Gift for a genius
---
[Scene: Kenta's Room - January 6th, Morning]
(Kenta wakes up. The room is quiet. No messages yet. He stretches and looks at the scarf and gloves from yesterday.)
Kenta: (thinking) "They really went all out."
(His phone buzzes. Group chat.)
Sui: "Kenta-kun! Are you awake?!"
Yui: "We have one more gift! The REAL gift!"
Sui: "Meet us at school early! Before classes!"
Yui: "It's big! Like literally BIG!"
Kenta: (confused) "Big?"
Sui: "JUST COME! "
Yui: "See you soon! "
Kenta: (staring at phone) (thinking) "What could be bigger than handmade gifts?"
---
[Scene: School Entrance - Early Morning]
(Kenta arrives. Sui and Yui are waiting with a large wrapped object behind them. It's tall. Wide. Clearly heavy.)
Sui: (jumping) "KENTA-KUN! YOU'RE HERE!"
Yui: (also jumping) "HAPPY BIRTHDAY... AGAIN!"
Kenta: "My birthday was yesterday."
Sui: "BIRTHDAY WEEK! WE TOLD YOU!"
Kenta: (looking at the object) "What is that?"
Yui: (grinning) "Your REAL gift!"
Sui: "The scarf and gloves were just warm-ups! This is the main event!"
(They step aside. The wrapped object stands there, mysterious.)
Kenta: (approaching) "Can I... open it?"
Sui: "PLEASE DO!"
(He pulls the wrapping off. Reveals a large whiteboard. Professional grade. Standing on wheels. Marker tray full of new markers and erasers.)
Kenta: (freezing) "..."
Yui: (nervous) "Do you like it?!"
Sui: (also nervous) "We know you're always solving problems on paper. But paper runs out. Whiteboard is forever!"
Kenta: (still frozen) "..."
Yui: (panicking) "Kenta-kun?! Say something!"
Kenta: (quietly) "It's... perfect."
Sui: (tearing up) "Really?!"
Kenta: (touching the smooth white surface) "I can write anything. Erase anything. Start over. Infinite space for infinite problems."
Yui: (also tearing up) "We wanted you to have space. For your genius."
Sui: "No more tiny papers! No more running out of space!"
Kenta: (turning to them) "How did you afford this?"
Sui: (shyly) "We saved up. For months."
Yui: "Worked part-time jobs. Skipped snacks."
Kenta: (staring at them) "You did that... for me?"
Sui: (nodding) "You're worth it."
Yui: (also nodding) "Always."
(Kenta's ears are red. His eyes are slightly wet. He blinks rapidly.)
Kenta: (voice rough) "No one has ever... given me something like this."
Sui: (hugging him) "Get used to it!"
Yui: (joining the hug) "We're just getting started!"
Kenta: (stiff, but not pulling away) "Thank you. Both of you."
Sui: (muffled against his chest) "You're welcome."
Yui: (also muffled) "Happy birthday, Kenta-kun."

[Scene: Transporting the Whiteboard]
(Getting the whiteboard to Kenta's hostel is an adventure.)
Sui: (carrying one side) "It's heavier than it looks!"
Yui: (carrying the other) "Why are buildings so far apart?!"
Kenta: (carrying the base) "I could have carried it alone."
Sui: "NO! TEAM EFFORT!"
Yui: "BIRTHDAY TEAM!"
(They stumble through the streets, attracting stares.)
Old Lady: (watching) "Young love. So cute."
Sui: (face red) "IT'S NOT—WE'RE NOT—"
Yui: (also red) "JUST FRIENDS!"
Kenta: (calmly) "They're my childhood friends."
Old Lady: (smiling) "Of course, dear. Of course."
(She winks. Sui and Yui die inside.)

[Scene: Kenta's Room - Whiteboard Installation]
(They manage to get it inside. It dominates the small room now.)
Sui: (stepping back) "It fits! Barely!"
Yui: (also stepping back) "Now your room looks like a real genius lair!"
Kenta: (already writing on it) "E = mc²..."
Sui: (laughing) "He's already using it!"
Yui: (also laughing) "Didn't even wait for us to leave!"
Kenta: (turning) "Sorry. I got excited."
Sui: (softening) "Don't apologize. It's YOUR board."
Yui: (grinning) "Show us something!"
Kenta: "Something?"
Sui: "Something cool! Genius stuff!"
Kenta: (thinking) "Okay."
(He picks up a marker. Starts writing.)
---
[The Whiteboard - First Use]
Kenta: (writing) "The Riemann Hypothesis..."
Sui: (reading) "What's that?"
Kenta: "One of the hardest unsolved problems in mathematics. It deals with the distribution of prime numbers."
Yui: (eyes glazing) "Prime numbers?"
Kenta: (continuing) "The zeta function ζ(s) has zeros at negative even integers. But the non-trivial zeros... if Riemann is correct, they all lie on the critical line Re(s) = 1/2."
(He fills half the board with complex equations.)
Sui: (staring) "I don't understand any of this."
Yui: (also staring) "But it looks impressive!"
Kenta: (pausing) "You don't have to understand. You just gave me space to try."
Sui: (quietly) "Do you think you'll solve it someday?"
Kenta: (looking at the board) "Maybe. Probably not. But I can try. That's what matters."
Yui: (smiling) "That's our Kenta-kun."

[Scene: Testing the Board]
(They spend the next hour playing with the whiteboard.)
Sui: (drawing a stick figure) "Look! It's Kenta-kun!"
Yui: (adding another) "And Sui! And me!"
Kenta: (watching) "You're drawing on my serious math board."
Sui: "It's MULTIPURPOSE!"
Yui: "Math AND art!"
Sui: (adding hearts around the figures) "There! Perfect!"
Kenta: (looking at the drawing) "Why are there hearts?"
Sui: (face red) "AESTHETICS!"
Yui: (also red) "VISUAL APPEAL!"
Kenta: (almost smiling) "Sure."
(He picks up a marker. Adds equations inside the hearts.)
Sui: "What's that?"
Kenta: "The formula for love."
Sui & Yui: (in unison, exploding) "WHAT?!"
Kenta: (calmly) "Mathematically, love can be modeled as a chemical reaction. Dopamine, serotonin, oxytocin. The equation represents the probability of emotional bonding given shared experiences."
Sui: (deflating) "Of course he made love into chemistry."
Yui: (laughing) "That's so Kenta-kun!"
---
[Scene: Evening - The Board in Use]
(Kenta stands before the whiteboard, solving problems. Sui and Yui sit on his bed, watching.)
Sui: (whispering) "He's been at it for hours."
Yui: (whispering back) "He's in his element."
Sui: "Our gift did this. We made him happy."
Yui: (smiling) "Yeah. We did."
Kenta: (without turning) "I can hear you."
Sui: "WE KNOW!"
Yui: "JUST APPRECIATING YOU!"
Kenta: (almost smiling) "Appreciate quieter."
Sui: "NEVER!"

[Scene: Night - The Girls Leave]
(They stand at the door.)
Sui: "Kenta-kun... do you really like it?"
Kenta: (looking at the whiteboard) "It's the best gift I've ever received."
Yui: (tearing up) "Really?"
Kenta: "Really. No one has ever given me something that helps me think. That helps me grow. You saw me. The real me."
Sui: (crying) "Kenta-kun..."
Yui: (also crying) "That's so beautiful..."
Kenta: (ears red) "Don't cry. It's just a whiteboard."
Sui: "IT'S NOT JUST A WHITEBOARD! IT'S US! CARING ABOUT YOU!"
Yui: "AND YOU GETTING IT!"
Kenta: (quietly) "I get it. I get you."
(They hug him. Tight. Long.)
Sui: (pulling back) "See you tomorrow, genius."
Yui: (also pulling back) "Solve good problems!"
Kenta: (nodding) "I will."
(They leave. He closes the door. Looks at the whiteboard. At their drawing still there. At the equations surrounding it.)
Kenta: (touching the hearts) "The formula for love."
(He almost laughs.)
Kenta: "Maybe not chemistry. Maybe something else."

[Scene: Kenta's Room - Night]
(He lies in bed. His phone buzzes. Two messages.)
Sui: "Kenta-kun! So happy you loved the whiteboard! We were so nervous! Sleep well and fill it with genius! "
Yui: "My prince~ watching you get excited over math was the cutest thing ever! That board is yours forever! Just like us! Goodnight!"
Kenta: (smiling) (typing back to both): "Goodnight. Thank you for the perfect gift. I'll use it every day. And I'll keep your drawing on it forever."
(Immediate replies:)
Sui: "HE'S KEEPING OUR DRAWING! "
Yui: "THE HEARTS! HE'S KEEPING THE HEARTS! "
Sui: "SWEET DREAMS OUR GENIUS!"
Yui: "FILL THAT BOARD WITH BRILLIANCE! "
Kenta: (putting down the phone) (looking at the whiteboard across the room)
Kenta: (thinking) "January 6th. The day I got space to think. And people who care."
(He closes his eyes, smiling.)
Kenta: (thinking) "Best birthday week ever."
