Hitoribocchi no Marumaru Seikatsu

Hitori Bocchi has severe social anxiety, making even a simple conversation with someone new feel terrifying. Through elementary school she had only one friend, Kai Yawara, but the two enter different middle schools. Hoping to push Bocchi toward relationships beyond herself, Kai cuts contact and promises they can be friends again once Bocchi befriends everyone in her new class. The challenge begins with Nako Sunao, the intimidating-looking girl in the seat ahead of her. Every greeting and conversation becomes a full test of Bocchi's nerves, yet each new friendship teaches her that perfect plans matter far less than finding the courage to try again after an awkward failure.
