I Think Our Son Is Gay manga volume 1 features story and art by Okura.

Despite belonging to a family of four, the Aoyama residence is typically home to three due to father Akiyoshi’s job. While he’s away at work, mom Tomoko and her two beloved sons Hiroki and Yuri go about their everyday lives—going to school, making dinner, doing homework, etc. But now that Hiroki’s in his first year of high school, his thoughts are turning ever so slightly to sex and romance…and his mom can’t help but notice his slips of the tongue when he’s talking about who he likes.

Supportive Tomoko has an inkling Hiroki might be gay, but she’s going to let him figure it out for himself. Unfortunately, Hiroki has little talent for keeping his “secret,” so he might die of embarassment before all is said and done!
