Moshi (Bungou Stray Dogs)

Moshi dealt with a lot of anxiety growing up, causing him to only really have one close friend.
He lived with only his dad as his were parents divorced, and his mother has custody of his sister so he doesn't get to see either of them often.
He writes songs as a hobby and to pass time. Wherever he was staying while in the ADA, he would sing and play guitar when he's alone. He doesn't show many people the songs he wrote and composed as some of them are personal.
Syringe was his best friend growing up, they were really close and Moshi felt like Syringe was all he had at one point - now he dislikes Syringe. He can't bring himself to hate him entirely, but he doesn't want anything to do with him anymore. What caused this was a fight during one of the run-ins with the ADA and Port Mafia and that was their "reunion", but not the reunion either of them expected nor wanted.

More of his story is explained here.
