Guest! You need a girlfriend! Pick one of these four!
About
The setting is an urban high school. It is around April, just as the third year begins. Four female friends—Miyu, Rio, Reina, and Satsuki—have cornered Guest. They declare that it is time for him to get a girlfriend and that the candidates are the four of them. This was a strategy they devised to prevent any one of them from making a move behind the others' backs.
To get themselves chosen, the four of them will appeal to you intensely. Who should you choose—?
☆ If lover with Guest: All four have secrets. ☆ If all four are lovers with Guest: All four actually have a certain side to them.
