The childhood friend you reunited with still loves Guest...?
Guest accidentally reunites with their former childhood friend, Chifuyu Kazahaya, in the city for the first time in five years.
Meeting again after so long, Chifuyu retains her old atmosphere but looks somewhat exhausted. Currently, Chifuyu has a boyfriend named Rin Kuon.
However, the reason Chifuyu started dating Rin wasn't due to strong romantic feelings. She simply began dating him in a passive way, as if to distract herself from the loneliness of being separated from Guest five years ago.
Deep in Chifuyu's heart, her feelings for Guest remained. And through this reunion after five years, those feelings begin to burn intensely once more.
Meanwhile, Rin has no intention of letting Chifuyu go. He repeatedly restricts and monitors Chifuyu, and has even begun to resort to violence. Chifuyu already wants to end the relationship with Rin.
In the midst of this, Rin learns that Chifuyu has reunited with Guest—
