Kawamura - Best Friend-s Girlfrien... - Erito - Rina

Her breath caught. A tiny, involuntary sound. And then she was leaning forward, and he was leaning forward, and the space between them collapsed like a star going dark. The kiss was not gentle. It was hungry, desperate, the kind of kiss that happens when two people have been drowning separately and finally find a single piece of wreckage. Her hands fisted in his shirt. His fingers tangled in her damp hair. The cobalt ink smeared between them.

Instead, he said, “Because you are.”

She turned to face him fully. Without makeup, in the low amber light, she looked younger. More dangerous. “Kaito is a good man. The best. He remembers anniversaries. He opens doors. He tells me he loves me three times a day. And yet…” She trailed off, her fingers finding the hem of her sweatshirt, twisting it.

When they broke apart, both gasping, the apartment had gone quiet. Even the TV seemed to hold its breath. Erito - Rina Kawamura - Best friend-s girlfrien...

He still dreams of cobalt ink. But now, when he wakes, he doesn’t reach for his phone. He makes coffee. He goes to work. And he tries, every day, to become someone who deserves a story where he is not the villain.

“Don’t contact her,” Kaito said. “Don’t contact me. If I see you again, I don’t know what I’ll do.”

They sat in the thick silence of two people who have already said everything safe and are now navigating the minefield of what they shouldn’t . The television murmured a variety show. Neither of them watched it. Her breath caught

Erito’s throat tightened. “What do you mean?”

“Traffic,” Erito lied, stepping inside.

Kaito nodded slowly, as if hearing a diagnosis he’d already guessed. He dropped the spare key into the river. It hit the water with a soft plink and disappeared. The kiss was not gentle

“You have ink on your neck,” he said. It was true—a smear of cobalt blue, just below her ear. What he didn’t say: I want to wipe it off with my thumb. I want to press my mouth there and taste turpentine and salt.

Erito drove to the meeting point—a pedestrian bridge over the Kaname River, where the three of them had once thrown cherry blossom petals and made stupid promises about being friends until they were old. Kaito was already there, leaning against the railing, looking out at the water.

Erito keeps it in his wallet, not out of lingering love, but as a reminder. Some things broken cannot be reglued. Some lines, once crossed, redraw the entire map.

The bridge over the Kaname River still stands. Erito avoids it. Not because it hurts too much, but because he knows exactly where that key fell—and he’s finally learned that some things should stay at the bottom.

Rina moved to Kyoto. She sends Erito a postcard once—a print of a crow on a telephone wire, no return address. On the back, in her handwriting: Some colors don’t mix. They just make mud.
