Do you think you can make some afo angst plezzzz?
Of course 🥰
After he accidently killed Yoichi I like to think he entered a deep state of depression for a while. He's never been without his brother before in his life and he felt uneasy and sick at the thought of having to spend the rest of his life without him. He kept constantly having nightmares of seeing Yoichi's body explode into pieces that day and got little to no sleep as a result. He didn't eat much at all and was in a near catatonic state wondering if any of it was even worth it without his brother there. It was only the realization that a part of Yoichi is still out there (OFA) that brought him out of it.
But even after that throughout the years I think being without his brother had him experiencing depression slumps at times that hit him out of nowhere and made it difficult to function. He probably keeps some of his old clothes and buries his face into them trying to inhale whatever's left of Yoichis scent so he could pretend he's still there next to him. He thinks about Yoichi everyday and doesn't see life worth living without him. What happened down in the sewers is his greatest regret.
