His lil brother
the lead singer that the main couple met at the uke's mother's hometown
Family member. I think his brother… they mention it either earlier in the story or in the main couple’s story
Adoptive brother biological cousin.
They were the same person!? In this story everyone knows everyone
Yass, its the same person. I cant exactly remember but it showed a glimpse from either Otoha or Yanagi sensei's flashback
Wait!!! Who is this otoha guy ?????
