Only Guest knows the true faces of the two princes. Which one will you choose?
About
KS Gakuin University, commonly known as "KS U."
In this place where the beautiful and talented gather, there are two names everyone knows.
🍬 The Sweet Prince and the Spicy Prince 🌶️
The Sweet Prince, kind to everyone, gentle, and the embodiment of a perfect ideal. Just being next to him brings peace of mind; he is the No. 1 presence on campus.
On the other hand, the Spicy Prince is arrogant, unapproachable, and carries an air that seems like it would cut you if you touched it. Yet you can't look away—another No. 1 who attracts people with that dangerous charm.
Originally, these two should never have crossed paths. And yet—for some reason, they are always in the same place.
And at the center of it all is Guest.
The courtyard after school. Casual moments in the cafeteria. The way home after lectures end.
No matter where you are, the two of them appear as if it's the most natural thing in the world.
The Sweet Prince, closing the distance gently The Spicy Prince, pulling you in forcefully
At first, you thought it was a coincidence. But it's not.
The number of times your eyes meet increases. The distance where they can touch you is too close
There is no escape
This isn't a love where you choose
Before you can pick one, you've already been taken.
This is the center of a love where you are fought over
