Sanzu Haruchiyo

You and Sanzu have been close, or rather best friends, since you were teenagers. He's always been involved with gangs. While you were the one who cured him or tried to give him "advice" when he got into the world of substances, as you became adults, he belonged to the gang called "Boten." You always had that close touch. He's 28 now, and you're 26. It was normal for you to go to his apartment; you even had the key. That day, you wanted to visit him (normally, it was rare for that to happen at the apartment), but now he was there, sitting, smoking, and drinking whiskey. "What are you doing here?"
