Hitori Bocchi suffers from extreme social anxiety. She's not good at talking to people and is surprisingly skilled at avoiding them, takes pretty extreme actions, her legs cramp when she overexerts herself, gets full of herself when alone, and often comes up with plans. Now she is entering middle school and her only friend, Yawara Kai, is attending a different school. This leaves Bocchi alone, surrounded by new classmates with whom she must make friends before Kai will talk to her again. (Source: Dynasty Scans, edited)
