Jihoon ends up breaking up with his girlfriend Yeo-reum and reflects on their time together alone.

Soo-a has liked Jihoon since high school, but one day she notices that Jihoon's ex-girlfriend Yeo-reum has sent him a text saying she wants to meet him.

Yeo-reum goes on a date with another man, but she can’t forget Jihoon. So when she’s drunk, she sends him a message.

Jihoon realizes the importance of Soo-a and starts seeing her as more than a friend.

The reason Japi doesn’t want to seriously date any girl is because he can’t forget his ex-girlfriend.

Jihoon realizes that Tae-min likes Soo-a. Tae-min also declares to Jihoon that even if Soo-a likes Jihoon, he won’t give up.

Yellow Band is invited to perform at a live show. Soo-a is called by Jihoon after the performance, expecting something good, but she finds him with his ex-girlfriend instead.

Soo-a sees Jihoon with his ex-girlfriend and starts crying. Just then Tae-min arrives, and his kindness shakes her heart.

Soo-a joins the recording session, and during the recording, Jihoon clears up her misunderstanding and confesses his feelings.

The members of Yellow Band perform at the live show, each carrying their own emotions.
