ワンサイドインルーム

Oka, a college student with bad eyes and who is kept away from others, is in love with Saeki, a good-looking guy from the same university. Shortly after entering the school, Saeki kissed him and said, "You're cute," as a new member of the club, and he suddenly approached him. After that, they were completely absorbed in the house, and they ended up doing more than just kissing. Oka thinks that Saeki is interested in him on a whim, but contrary to his seemingly relaxed attitude, Saeki is also becoming serious about Oka.
