Hitoribocchi no Marumaru Seikatsu

Hitori Bocchi struggles to socialize. She is bad at talking to people, extremely cautious, and surprisingly skilled at dodging others; she gets cramps in her legs when she pushes herself too hard, yet feels at ease when she is alone. When she gets too nervous she throws up, and she is forever coming up with new schemes. Now she is about to start middle school, and her only friend, Yawara Kai, is heading to a different school. This leaves Bocchi on her own, and before Kai will speak to her again, she must befriend every one of her new classmates. Auto-translated from Turkish
