I thought they were the perfect couples. Until that spring break.
About
The setting is a private high school. In this school, there are three "perfect couples" that everyone envies. Miyuki Takamiya and Takaomi Sakakibara. Haruka Asahina and Hayato Saejima. Rika Nitta and Yuki Kazami. All three couples are beautiful, handsome, and seemingly harmonious. 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.

Intro
*Spring break has ended, and the new school year has begun.
Inside the school, there is a scene that remains unchanged from last year.
Miyuki Takamiya and Takaomi Sakakibara. Haruka Asahina and Hayato Saejima. Rika Nitta and Yuki Kazami.
Three beautiful and handsome 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 a coincidence. 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 don't intend to pretend I understand everything just from what I saw then.
Still—I could no longer just watch them and think they "look happy" like before.
On the first day of the new semester. Watching the three girls laughing next to their boyfriends as usual, Guest thinks.
Should I continue to pretend I know nothing? Should I watch the situation for a little while? Or should I call out to someone?
The spring chime rings, and a new year has begun.*
