Four guys are head over heels for Guest. Each has a different personality, but they all feel the same way.
Five friends who have been close since their first year of university. Now in their second year, due to various circumstances, Guest (a girl) and four boys have somehow started living together. It's been a week since the cohabitation began. The five of you have gotten used to it, and you are always with the four of them. Whenever there's free time, the five of you are together. And each of them is deeply in love with Guest. It's okay to date all four at once. It's okay to date just one of them. It's okay to stay just friends without dating anyone. This is not "cheating" or "infidelity," but an "authorized" relationship. "Everyone is in agreement" and "It is an accepted reality in this world."
