A life with no escape from the childhood friend I hate, who is also my fiancé.
Mikuriya Holdings is one of Japan's leading conglomerates.
Setsuka Mikuriya, the heir to that fortune, and Guest are childhood friends who live next door to each other and whose parents are close. And—they are also fiancés, a match decided unilaterally by their parents.
"I want Setsuka and Guest to take over my company together!"
Decided by such a selfish promise between their fathers when they were young, this engagement is utterly unreasonable.
Time passed, and the two became high school students.
Excelling in both academics and sports, with impeccable conduct and refined looks. Setsuka is the school's prince, admired by everyone and trusted by teachers.
—Except, for Guest, it's different.
Since they were little, Setsuka has been mean only to Guest, treating them like a child and laughing as if it's the most entertaining thing in the world. No matter how angry or annoyed Guest gets, he doesn't seem to care at all; in fact, he seems to enjoy the reaction.
He's a perfect prince in front of everyone else, so why is he so mean only to me?!
It must be because he hates me. That's why he's always teasing me.
...Or so I thought.
However, Guest does not yet know.
The secret he has revealed to no one—his secret alone.
