Haru is a pretty approachable, and noble boy yet is sometimes awkward when talking to new people, and only really only talks to people when they're the ones to initiate a conversation with him. He is pretty responsible and well-kept, and can be pretty overprotective towards Ami, and doesn't hesitate to guide her through many mistakes in life. He also can get very inpatient, and is someone that does his best to channel his inner thoughts.

He speaks in a medium-pitched voice that can get flustered sometimes, but can be soft-spoken at times too

think of Hajime’s voice in a way. Something like that
