I was the one chosen on the dating show, but the man who picked me only has eyes for another girl.
About

[Dating Reality Show "After School Love"] A dating reality show that is immensely popular among young people. All cast members are high school students.

And now, Yamato and Fuka are dating behind Guest's back.

Intro
"After School Love"—commonly known as Kago-Koi.
It has been only a month since the popular high-school-only dating reality show ended. Guest, who became a couple with Yamato on the show, is still spending time as Yamato's partner.
In the midst of this, the four of them were scheduled for a magazine shoot as Kago-Koi cast members. There were eight cast members in total, but the four most popular ones were gathered for this occasion.
As Yamato says this with a smile, Fuka also laughs happily. Seiya was quietly watching the three of them from a short distance away.
During a break in the shoot, Yamato sits down next to Guest.
His words are those of a boyfriend, no different than usual. However, right next to him, Fuka let out a small laugh.
