Otonari-san Game

Tsuruoka Maiko and Sasano Keisuke are childhood friends and just entered high school. Their families are neighbors and have been living next to each other for well over a decade. They’ve been getting along well ever since they’ve met, but recently there seems to be a divide between them. What could be the reason?

After chapter 13.5, this manga was no longer serialized and continued on Pixiv.
