In the Bonten!Timeline, the only things who make Inupi sure that Koko was alive were the anonymous and luxurious gifts sent to him at christmas and for his birthday. And the flowers put on Akane's grave one time by year. Meanwhile Koko kept a photo of Inupi on him all time, and changed it every years, for a more recent.
This is very emotional :')
I imagine Seishu waking up on a holiday morning, perhaps his birthday, discovering the delivery man on the other side of the door. Maybe he lives alone on the money he's made working on D&D, or maybe he shares a flat with Draken because he doesn't have enough to live on his own.
Still, he'd yawn and say he haven't ordered any packages, but the delivery man would show you his name and address and an anonymous sender. Then Seishu's head would click and he would take it without saying anything. He would quietly go back upstairs to his room and sit still on the bed looking at the package. It may not be elegant. It's brown and dull, but the interior is the complete opposite.
Who knows? Maybe it's those nearly $600 Dolce & Gabbana stiletto heels he've been eyeing for future purchase. Kokonoi knows how to read him even years later, in Bonten's shadow, trying not to be corrupted by everything that happens around him. Trying just for Seishu.
He knows everything and knows about his tastes because he has been by his side, although not long enough not to regret having missed. He might have parked his car across the street from D&D Motors just to see him come in. Maybe Sanzu knew about it —I'm sure Sanzu secretly controls everyone's lives to make sure no one is a possible traitor— and got so mad at him.
Even with everything, Kokonoi is still there. Seishu knows it. It's like a presence that accompanies him and weighs on his shoulders like the uncomfortable reminder of conversations they never had. He probably feels guilty, empty because Kokonoi can't see him trying on heels in front of his mirror and smiling weakly. At night, it becomes more painful.
The box has been recycled and the heels are in his closet, but it's not enough. He doesn't want gifts, he wants him and he knows he can't reach him. Even if a decade has passed, Seishu would be sure Kokonoi hasn't changed. Perhaps he dreams of him and can see again those dark, slanted eyes, the silky black hair, even if he doesn't know that Kokonoi has bleached it.
And Kokonoi would be afraid. Afraid of getting too attached to him, of having to push him away because of his work. He would be so afraid of meeting Seishu that he would never do anything but send anonymous packages. He wouldn't want him to know what he's been doing, or with whom, not even about how dirty his hands are, how rotten his heart is.
The last and only shred of humanity that would remain in him would be Seishu.
I'd like to think about a reunion for the sake of my sanity or the opposite.
Perhaps in Seishu coming home at night, after staying up in the middle of the night fixing a motorcycle. In the middle of the empty streets, he is attracted by some whimpering coming from an alley, where Kokonoi would be bleeding from a gunshot wound.
Kokonoi would think he was delirious with the figure of Seishu. He would raise a red-spattered hand to caress his face, while Seishu would go crazy trying to pick him up and get help. Seishu would take him home when Kokonoi pleaded they couldn't go to a hospital or they would definitely kill him.
Who knew what trouble he would have gotten into, but Seishu would take care of him.
