古見さんは、コミュ症です。

Shoko Komi arrives at Itan Private High School and immediately becomes the most admired student in class, but her composure hides a severe communication disorder that leaves her unable to speak in social settings. Hitohito Tadano, the one classmate who notices, reads her blackboard confession and strikes a pact: he will help her make one hundred friends. With Najimi Osana's boundless social energy pulling them into school events and new encounters, the count begins.
