In a school full of passion and youth, the story between Eun-jae, Eun-you, Ha Lee-chan and Qing-ah is like a complex drama intertwined with love, friendship and responsibility.

It turns out that Eun-jae's conscience discovered that he cleverly lied about the arrival of the police, causing the gangsters to flee the scene.In order to protect the school's reputation and avoid unnecessary trouble, he quickly organized everyone to restore order on the scene.But at this critical moment, He Lican thought of the upcoming school anniversary performance.However, everyone was in tatters and stained with blood, which put He Lican in trouble.In order to solve this problem, they decided to go to the bathhouse to take a bath together. At the same time, Enjie also took the opportunity to ask Xianlu what happened that year.Fortunately, Xian Lu has escaped from those gangsters and embarked on the right path.

At the same time, Eun-gyeol was questioned by Ha Lee-chan for lying to Ha Lee-can. He had to make up a reason to study abroad to avoid being forced by his parents, which Ha Lee-can found acceptable.But the matter didn't end there. Enjie let Eunyou off the hook last night, which made Eunyou very angry.When Enjie found Eunyou, she resolutely rejected him because the last thing she could tolerate was being abandoned.

In order to protect his own interests, the school chairman tried to drive away Enjie, but Enjie was unmoved.Fortunately, the chairman appeared in time, stopped the chairman's actions, and reached a new agreement with Enjie: extend the contract for one month, on the condition that when the contract ends, Enjie will make Qingya smile sincerely to her father..

In order to seek forgiveness from Eunyou, Enjie decided to tell her his secret from the future.But Eunyou didn't give him this chance. She said she didn't want to be treated as a trophy by others.Eun-you's appearance at the school anniversary makes Eun-jae nervous, and Qingya feels very sad because she realizes that she can't compete with Eun-you.She gave the guitar pick she made to Ha Lican, but she did not go to the school anniversary performance.

During the school anniversary performance, Eunyou's appearance caused a sensation.However, when Yoon Sang-ah tells her that Eun-jae and Ji-hwan once performed together, Eun-you realizes that her mother and father once had a relationship.The discovery made it impossible for her to continue watching the show, and she ran outside and burst into tears.The music store owner saw this scene, but he did not reveal his identity.

The band's performance won the hearts of the audience, but during the last song, Ha Lee Chan dedicated the song to a girl.When the chasing light passed, Eunyou had disappeared.After the performance, Ha Li Chan wanted to go to Eun Yoo, but was stopped by female fans.Eun-jae takes the opportunity to run out, and the band members feel guilty for not being there at the celebration party.

When Qing Ya went home depressed, she saw Ha Li Can waiting for her at the door.Ha Li Can asked her why she didn't come to watch the performance, and Qing Ya gestured and said she couldn't hear.Ha Li Chan told her that music can not only be heard with the ears, but also with the heart.But Qingya didn't want to have too much entanglement with him, so she left a note asking him not to come to her again in the future.

On the other hand, Enjie apologized to Eunyou at the door of her house, but Eunyou said it was his fault and said they would never meet again.When Eunyou packed her luggage and was about to leave, she received a call from the owner of the musical instrument store telling her that she had found an assistant for her trip.Enjie realized that Eunyou was going to the United States and hurried to the airport to find her, but found Eunyou sitting alone on the roadside crying.Enjie comforted her, saying that he would help her find a way back, and that he had figured it out, no matter who she was, as long as they could stay together.
