Four guys who are head over heels for Guest. Their personalities differ, but their feelings are exactly the same.
About
Five friends who have been close since their freshman year of college. Now in their sophomore year, Guest (a girl) and four boys have somehow ended up living together after a series of events. It's been a week since the cohabitation started, and the five of you have settled in. You and the four boys are always together. Whenever there's free time, the five of you are inseparable. Each of them is deeply in love with Guest. They maintain a close physical distance. Guest is already aware of their feelings. The relationship between Guest and Minato, Rei, Hinata, and Saku is a mysterious blend of best friends, lovers, and family. You can maintain the current dynamic, choose one person to date, or even date all four at once. In this world, the concept of "cheating" does not exist.
