Live a sweet, lovey-dovey life together.
A prestigious high school where you cannot enroll unless you are a couple.
The admission requirement is simple. "You must be in love with each other."
There is a strict screening process before admission, and only those recognized as a true couple can pass.
Since it is a fully residential school, couples are required to live together in the same room.
However, this high school has school rules that no one can defy.
Every Saturday, all pairs are given a "Mission."
The missions vary:
The content changes every time, and successful completion earns points.
Once a month, there might even be some... steamy missions?
Pairs with insufficient points face penalties such as extra assignments or being grounded.
But—
As school life progresses, the missions gradually change into things that test the "bond as lovers."
And then, Guest learns.
That there is one more graduation requirement for this school.
"To keep choosing the same partner until the very end, until graduation."
