School Trip: I joined A Group I'm Not Close To

When deciding on groups for the school trip, Hioki somehow ends up being invited to join a group of four handsome guys. Hioki was anxious about the trip, but it turned out to be more fun than he expected...? He was able to spend such a peaceful time thanks to Watarai, who was always looking out for him. Just as he began to open up to this kind-hearted boy, as they gradually became closer, he started to realize that what he saw wasn't kindness… but rather, obsession…?!
