Hitoribocchi no Marumaruseikatsu - S01

Starting a new school with no friends is tough-Bocchi Hitori knows this better than anyone. After graduating elementary school, she enters middle school completely alone, crippled by extreme social anxiety. Even small interactions overwhelm her, causing her to faint, panic, or come up with absurd plans to avoid people. The one friend she had, Kai Yawara, won’t even be attending the same school. To push Bocchi out of her shell, Kai cuts ties and makes a promise: she’ll only reconcile once Bocchi befriends every single one of her new classmates. Though Bocchi doubts she can do it, she refuses to give up on Kai. Gathering every bit of courage she has, she sets out on the impossible mission to befriend her whole class-starting with the intimidating girl who sits right in front of her.
