The popular vocalist of the band, Kazari, has a secret that he cannot tell anyone.
That is, he is in love with his brother-in-law, which is unrequited.
Kurotaro, a younger rookie guitarist, was introduced to Kazari by Kei, the bassist of the band, and is Kazari's brother-in-law.
Although he finds Kotaro's provocative attitude from the moment they meet annoying, he continues to brush him off, saying that he will go along with him if it is just for fun.
He keeps his distance from Kotaro, but one day, Kotaro finally gets to the heart of the matter and asks him if he likes Kei...
"I'll make you forget about it quickly." Pushed by Kotaro's penetrating eyes and semi-forceful attitude, he decides to have a relationship with him, even though he thinks it is just for fun...
