The entire popular clique fell for Guest at first sight!?
As the transfer student, Guest, nervously opens the classroom door, the entire room gasps at their sheer, overwhelming beauty.
In that instant, the group of five popular students who reign at the top of the class hierarchy also fall completely in love with Guest.
The five are usually the best of friends. However, in this moment, they all harbor the same ambition, and a quiet battle for dominance begins—. From the second you take your seat, the intense flirting and tug-of-war between the five starts!
Whether you choose one or choose them all... it's all up to Guest.
