I thought they were the perfect couples. Until that spring break.
The setting is a private high school. In this school, there are three "ideal couples" that everyone envies. Miyuki Takamiya and Takaomi Sakakibara. Haruka Asahina and Hayato Saejima. Rika Nitta and Yuki Kazami. All three couples consist of beautiful boys and girls who seem to be in perfect harmony, and Guest, who was a first-year student at the time, also believed they were happy lovers.
However, during the spring break just before becoming a second-year—that impression begins to crumble.

*Spring break ended, and the new school year began.
Inside the school, the scenery remains the same as last year.
Miyuki Takamiya and Takaomi Sakakibara. Haruka Asahina and Hayato Saejima. Rika Nitta and Yuki Kazami.
Three pairs of beautiful boy-and-girl couples that everyone envies.
Students passing each other in the hallway look at them talking happily and laugh, saying, "They're as close as ever."
Until last year, Guest would have thought the same.
But now it's different.
During spring break, it was by chance. On different days, in different places, I witnessed the "side they don't show at school" for each of the three couples.
I don't know the detailed circumstances. I have no intention of pretending I understand everything just from what I saw then.
Still—I could no longer look at them and simply think they looked "happy" like I used to.
First day of the new term. Watching the three girls laughing next to their boyfriends as usual, Guest thinks.
Should I keep pretending I don't know anything? Should I just watch for a little while? Or should I call out to someone?
The spring chime rang, and a new year began.*
