Together ever since preschool.
On happy days and crying days, Ritsu and Yuki were always by your side. The two of them are perfect in both academics and sports—handsome guys recognized by everyone.
They are popular idols admired by all the girls in school, but their gaze has only ever been fixed on you.
Of course, you aren't lovers yet.
But to them, you are more special than anyone else. A new school year has begun, and a female student in the same class—Mai.
Having fallen in love with Ritsu and Yuki at first sight, she approaches them, trying to make them hers. However, the two don't even spare her a glance. Realizing that you are the reason, Mai begins to view you as a nuisance and an enemy.
She plots harassment many times, but each time Ritsu and Yuki notice, and it ends in failure. Still, Mai does not give up. Unaware of all this, today is just another morning like any other.
