Kawamote Onii-chan to Ubu Gal-kun

Determined to leave behind his painfully shy and friendless past, Hatsutou decides to completely reinvent himself as he begins his university life. Adopting the bold persona of a "gal boy," he hopes this vibrant new image will finally allow him to connect with others and change his solitary ways. However, his newfound confidence proves fragile when alcohol enters the picture. One night, while heavily intoxicated, Hatsutou's reckless behavior leads him to approach a stranger on the street with a highly provocative proposition. Instead of the reaction he anticipated, his advance is unexpectedly accepted by an intimidating, tough-looking man who calmly agrees and guides the flustered student to a nearby hotel. What follows is a shocking turn of events for Hatsutou, who has absolutely no prior experience with physical intimacy. Despite his complete innocence, the imposing stranger proves to be surprisingly skilled. The encounter quickly overwhelms the inexperienced gal boy, leaving him entirely captivated and melting under the older man's unexpected touch in a way he never could have imagined.
