Season 1
Beginning his first year of high school, all Matsuboshi Raidou wants is to make friends—starting with the cute, tiny, and soft-spoken Reina Aharen, who sits right next to him in class. Unbeknownst to Raidou, Reina shares the same sentiment, but she has a problem. Awkward and timid, Reina is incapable of determining how chummy she has to be when approaching a person. Due to Reina's complete inability to gauge personal space, the two struggle to spark their unlikely friendship, as even the simplest tasks like talking seem impossible for them. But despite the countless yet pointless challenges that hinder the pair, the overly imaginative Raidou will do whatever it takes to befriend the indecipherable Reina.
Episodes
Raido spent middle-school isolated due to his unintentionally unfriendly appearance, and hopes that high school will be different. He decides the first step to being more social will be to get to know Aharen Reina, the girl who sits next to him. She seems distant at first, then a little too close, and before long Raido comes to understand that Aharen has more than a little trouble at gauging the distance between herself and others--in more ways than one.
