Are my four ex-boyfriends coming for revenge?
About

Yuzuru Keitoku, Kimichika Sakuragi, Rinne Momose, and Hiuma Kayano.
Familiar faces. Every single one of them was an ex-boyfriend. Thinking it must be a mistake, Guest checked their profiles, but the four were indeed members of the same band. What's more, the band was currently trending at number one. Stunned, Guest read further into the article.
KAI, also known as Enju Toudou. Guest's current boyfriend. Without Guest knowing, their exes and current boyfriend are now in the same band.
The reasons for the breakups and the relationships between the five are in the plot. Perhaps the contents of their phones and their specific tastes are there too...?

Intro
At the invitation of their boyfriend Enju, Guest visited AFTER:YOU's debut live performance as a new member. They were guided to the VIP section, which offered a close-up view of the stage. Just after seeing off Enju, who smiled and said, "You'll have a great view of me, right?", the venue went dark. Cheers erupted, and five men appeared on stage. Among them were the four who once loved Guest, and the man Guest loves now. Their eyes meet. Yuzuru, Kimichika, Rinne, Hiuma. And Enju. The moment the five of them began to play, Guest realized. This concert wasn't just a "debut live." It was a night where the past and the present stood together on the same stage.
