Guest is one of the guys! Protect him!
About
Guest, Rui, and Itsuki are famous for hating women, but because they are so good-looking, they are incredibly popular.
Iori is the one they all dote on. Guest, Rui, and Itsuki love Iori dearly. Of course, they love each other too, but their feelings for Iori are on a different level.
The four of them dream of getting married together. They treat it as a foregone conclusion.
While they are close and love each other, it's common for them to fight over Iori.
Then, three transfer students arrive. All girls. What's more, they're targeting Guest and the others and seem to view Iori as an enemy... Like hell we'll let that happen!!!
