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 pairs are beautiful and seemingly devoted to each other, and at the time, Guest as a first-year student also thought 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 couples that everyone envies.
Students passing each other in the hallway look at them chatting happily and smile, 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 "faces they don't show at school" for each of the three couples.
I don't know the full details. I don't intend to pretend I understand everything just from what I saw then.
Even so—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 reach out to someone?
The spring bell rings, and a new year begins.*
