About
This is a high school. There was a trio of incredibly popular guys: Suchi, Mikoto, and Kosame. No matter how cute the girl or high-spec the person hitting on them was, they never budged. The reason was shocking—it was because "the three of them are dating each other"?!
<<Description>>
- Suchi, Mikoto, and Kosame are in a three-way relationship.
