There were things I hadn't told Kaien.
And there were things Kaien hadn't told me.
And there was Ren, who had apparently decided that the best way to handle both of those facts was to corner me alone in the safehouse kitchen at six in the morning and make an absolutely terrible pot of barley tea.
I watched him pour it with the expression of a man attempting a procedure he'd read about once but never practiced. The water was still steaming when it hit the cup. He pushed it toward me across the worn wooden table and sat down with the air of someone who had rehearsed what they were about to say and was already unhappy about it.
"You should know," he said without preamble, "that Kaien hasn't slept properly in four days."
I wrapped my hands around the cup. "I know."
"He stood outside your door for an hour two nights ago. Just standing. Then he left."
I looked up.
Ren met my eyes steadily. He had a round, honest face — the kind that made people underestimate him, which was exactly why Kaien kept him close. His loyalty was the particular kind that didn't require saying out loud because it was visible in everything he did.
"Why are you telling me this?" I asked.
"Because he won't," Ren said simply. "And because you need to understand that whatever calculation you're running in that head of yours — whatever wall you're still maintaining between yourself and what you actually want — he's doing the same thing on his side, and between the two of you I'm getting very little sleep."
Despite everything, a small laugh escaped me. "That's not my fault."
"With respect," Ren said, in the tone of a man who was about to be deeply disrespectful, "it's both of your faults. He protects everything he loves by keeping it at arm's length so he can't watch it get destroyed. And you —" He paused. Considered. "You've been here before, haven't you? Not this exact situation. But something like it."
I went still.
"He told me," Ren said carefully. "What you said. About nine lifetimes. He didn't explain it — he wouldn't — but he looked the way he looks when something has rearranged his entire understanding of the world and he hasn't decided what to do about it yet."
The tea was too hot to drink but I lifted it anyway, just to have something to hold.
"What do you want me to tell you, Ren?"
"Tell me the truth," he said. "Not because I'll judge you for it. But because I've protected that man with my life for six years, and I'd like to know what I'm actually protecting him toward."
The kitchen was quiet. Outside, the capital was beginning its morning sounds — wheels on stone, voices carrying across the cold air, the distant bell of a temple marking the hour. A completely ordinary day in a city that had no idea its emperor was dying and its second prince was building a shadow army in its gut.
I set down the cup.
"I don't know how to explain it," I said. "Not in a way that sounds sane."
"Try."
"In every lifetime I can remember," I said slowly, "I have loved him. And in every lifetime, he has died. Sometimes in battle. Sometimes by illness. Once —" I paused, the memory of a cold riverbank pressing up through the present. "Once because of me. Because someone was trying to get to me and he stepped in the way." I breathed. "This life is different. I don't know why. But I know — I have known since I first saw him in this body, this time around — that this is the one that matters. This is the one where I can change it."
Ren was quiet for a long moment.
"And does he know all of this?" he asked.
"He knows some of it. Enough to believe me, I think. More than anyone else ever has."
"What does he think about it?"
I smiled despite myself. "He thinks about it the way he thinks about everything. Thoroughly. Quietly. From three feet away, where he can see all the exits."
Ren made a sound that was almost a laugh. Then he picked up his own cup and wrapped both hands around it and stared into it for a moment.
"He's afraid," Ren said quietly. "Not of dying. He's never been afraid of that." A pause. "He's afraid of what happens if he lets himself want something. Because every time he has — his father, his unit, the people he's tried to protect — it's been taken from him. And he's rational enough to know that's not cause and effect. But that's how it feels."
"I know," I said.
"And you?"
"I'm afraid of the same thing," I said. "Just in reverse. He's afraid of wanting. I'm afraid of hoping." I turned my cup in my hands. "Nine times is a long time to hope."
We sat in that together for a moment — the particular heaviness of two people who cared about the same person understanding each other across a shared grief.
Then Ren said: "He's going into the archive tonight. He didn't want you to know."
I set down my cup so fast the tea sloshed over the rim.
"What?"
"He didn't want you in the Second Prince's study again," Ren said, with the look of a man delivering information he suspected might cause violence. "He adjusted the plan. He's going in himself, through the servant corridor."
"That corridor has guards."
"He knows."
"It has four guards and at least two of them are soldiers loyal to Ryeo-jun, which means if he's spotted —"
"He knows," Ren said again.
"Then why —" I stopped. The anger hit me in a specific, recognizable way — hot and sharp and directly attached to the image of Kaien bleeding in a corridor somewhere while I sat here drinking terrible barley tea. "Why didn't he tell me?"
Ren looked at me. Patient. A little sad.
"Think about it," he said. "You just told me he's afraid of watching things he loves get destroyed." A pause. "Why do you think he didn't tell you?"
The anger shifted. Changed shape.
I pushed back from the table.
"Where is he right now?"
"He left half an hour ago. He was going to scout the corridor layout first, then go in after the guard rotation at the second bell."
The second bell was in twenty minutes.
I was already moving.
"Areum," Ren called after me.
I stopped at the doorway. Looked back.
"He'll argue," Ren said. "When you find him. He'll say he had it handled, that you didn't need to come, that you should go back."
"I know."
"What will you say?"
I thought about nine lifetimes. About a cold riverbank and a man who'd stepped between me and a blade. About that single night in a borrowed room, his head against mine, his voice saying I believe you into the dark.
"I'll tell him," I said, "that I'm done letting him face things alone to protect me. That we either do this together or we don't do it at all." I paused. "And then I'll tell him I'm going in with him whether he agrees or not."
Ren nodded slowly. Something in his expression settled — resolved.
"Good," he said.
And I ran.
***
I found Kaien exactly where Ren said he'd be — crouched in the shadow of the servant entrance to the eastern wing, studying the guard positions with the focused intensity of a man completing a calculation he had no intention of sharing.
He heard me coming. He turned.
For a moment he just looked at me, crouched in the dark, this catastrophically controlled man who stood outside doors for an hour and said nothing and called it protecting.
"Ren," he said flatly. Not a question.
"Yes," I said, crouching beside him. "Walk me through the guard rotation."
"You should be —"
"Kaien." I turned to face him. We were close — close enough that I could see the faint tension in his jaw, the shadows under his eyes that Ren had warned me about. "I am not going back to the safehouse. I am not going to sit somewhere safe while you walk into a guarded archive alone. Tell me the plan."
His jaw worked.
"You're infuriating," he said.
"You tried to cut me out of a mission I built," I said. "I'm allowed to be here."
"I was trying to keep you from —"
"I know what you were trying to do." Softer now. "I know. But Kaien —" I held his eyes. "In every version of this, you die when you're alone. Not when you're with me." A pause. "So stop trying to protect me by removing yourself from my reach. It doesn't help either of us."
The silence held.
Then he exhaled — slow, from somewhere deep — and turned back toward the corridor.
"Guard rotation is four minutes," he said. "There's a thirty-second gap at the north turn. We go on my signal, and we don't separate once we're inside." He paused. "Stay close."
"Always," I said.
He glanced at me sideways.
And then he smiled — small, private, quickly gone — and turned back to the dark.
I pressed my shoulder against his and waited for the signal.
Together.
