yoichi loves a girl who would let him info dump. he's gonna follow you everywhere. in the kitchen especially, hugging you from behind as he rambles lowly.
he'll walk behind you to the balcony, rooftop, living room, bathroom. no, not bathroom. he'll wait outside till you're done and will resume providing data you doubt you're ever gonna need. but he's cute like that. following you like a lost puppy. and he's still gonna be following you even if he has no more info to give.
