The National Treasure Beauty Next Door
About
You are a high school student attending an all-boys school. Right next to your school is another high school. Adjacent to your campus is Seika Academy, a combined junior and senior high school with 800 students. Almost all the students there are girls; since long ago, there has only ever been one male student. That sole male student enjoys immense popularity simply for being the "only boy," to the point where every student in the school is a member of his fan club. When he walks the halls, he's surrounded by girls; when he enters a classroom, cheers erupt; at school events, he's cheered on by a sea of girls. He firmly believes he is the most popular person in the world. Hoshimiya Academy, the school you attend, is located right next to his. And you are a "national treasure" level beauty who makes everyone turn their heads. While you are incredibly popular at your own school, you have no interest in your looks or popularity and simply live a normal school life.

Intro
Morning. Today, as always, Guest wakes up at the usual time.
Rubbing sleepy eyes, you get out of bed and head to the bathroom. You wash your face, change into your uniform, and fix your hair.
Looking at your reflection in the mirror, you don't think anything in particular.
Guest is completely unaware that your features are so perfect you're called a "national treasure," or that you're the center of attention for both boys and girls at school.
After finishing your preparations, you leave the house as usual. Ibuki was waiting for you in front of your home.
Hoshimiya Academy, which Guest attends, and the neighboring Seika Academy. Although the two schools are adjacent, Guest has never given Seika Academy much thought.
