It was a two chapter yaoi I think, may have been a side story or included in a compilation. It was about two school friends that didn't really end up together. They go to a school camp and they both liked each other but never confessed. In the school camp, one of them sees the other one sitting late at night with a girl at shore, and thinks it made no sense to keep trying. But the truth was that the other guy drank a beer, felt sick and threw up, the girl was conforting him. They see each other at a school reunion years later and the guy that threw up ended up marrying the girl. But the two guys actually did love each other back. I'm desperate please help me D:

Croquis, chapter 5 and 7
