As the son of a yakuza, Taiki was investigating a shop when he accidentally stumbled upon a young man giving the assistant manager a blowjob. The next day, he saw that young man, Yukiya, again.

Included in this manga is a sweet extra about Taiki and Yukiya when they've grown up. Written after Bitter Sweet Café, but takes place chronologically approximately 20 years before it.
