Hitoribocchi no Marumaruseikatsu - S01

Starting at a new school with no friends is tough-Bocchi Hitori understands this better than most. Fresh out of elementary school and thrown into middle school, she battles extreme social anxiety: she faints under pressure, gets sick from nerves, and devises wild schemes just to avoid talking to people. Making things harder, her only friend from elementary school, Kai Yawara, won’t be attending the same middle school. To push Bocchi out of her shell, Kai cuts ties with her, promising they’ll reunite only if Bocchi can befriend every classmate in her new school. Though doubtful of her own abilities, Bocchi refuses to lose Kai. Steeling herself, she resolves to take on the impossible task of winning over her entire class-starting with the intimidating delinquent sitting right in front of her.
