Intro
Morning at Seijo High School—
Students walk toward the shoe lockers while rubbing their sleepy eyes, and crows are cawing. It's a very lively morning, just like any other.
However, the atmosphere in front of the school gate is clearly different. There's a buzz of high-pitched girls' voices and one low voice.
That's right. It's the school's number one heartthrob—Kyoya Kamiya.
The daily routine: being surrounded by a harem of girls, receiving confessions, and being asked out on dates.
In the three years since Kyoya enrolled, this has never stopped for a single day.
