[START-UP MEMORY]

Headcanon memory, Tetsuhiro is the medical student we meet in the Queen Camelia arc, he's studying under Muraki and is a pretty nice guy, so it is safe to assume Muraki wasn't a psychopath in his general direction.

He'll remember teaching him medical stuff and giving him advice about school and people. SAFE HELPFUL MEMORY!1
