Komi Can't Communicate. Volume 26: Tomohito Oda

The journey to 100 friends begins with a single conversation.
Socially anxious high school student Shoko Komi’s greatest dream is to make some friends, but everyone at school mistakes her crippling social anxiety for cool reserve. Luckily she meets Tadano, a timid wallflower who decides to step out of his comfort zone in order to help her achieve her goal of making 100 friends.
Tadano’s sister and mom are super supportive about his romantic prospects—they just somehow got the wrong idea about who he’s dating! So it comes as a bit of a shock to them when he introduces Komi as his new girlfriend. Awkwardness abounds, but after three years of intense training, Komi is ready to face the challenge of talking to her boyfriend’s family!
