After the operation, Song Jong-hyuk lost his memory because of a head injury in a car accident and forgot all the memories related to himself, and only his brother Song Jong-ki, who is an actor, accompanied him in the hospital. Lee Soon-gyu's face changed dramatically after learning that the injured person was Song Jong-hyuk, and he took the opportunity to visit Choi so-young to secretly go to see Song Jong-hyuk.

When Song Jong-hyuk went to visit Choi so-young, who was injured because of himself, he accidentally discovered that the two were old acquaintances. It turned out that Song Jong-hyuk was a trainee of ** company before he was admitted to university. Choi so-young declares that Song Jong-hyuk is her boyfriend, and Song Jong-hyuk, who wants to quickly retrieve his memory and return to his normal life, has no impression of this.

Kim Tae-yeon, who came to visit Choi so-young, originally had a bad impression of him because of Song Jong-hyuk's bad personality when he was a trainee, but when she saw Song Jong-hyuk's depressed and lonely scene, the soft-hearted Kim Tae-yeon comforted Song Jong-hyuk. Song Jong-hyuk plucked up the courage to ask her about her past self, but learned about Song Jong-hyuk's various bad deeds.

Disappointed in his past self, Song Jong Hyuk confides his distress to Song Hyuk, a senior doctor and life-saving benefactor, and Song Hyuk tells him that he should use it to face his past self and retrieve his memories to truly let go. Song Jong-hyuk regained his desire to regain his memory.

After being discharged from the hospital, Song Jong-hyuk was asked by his brother to move out of the school dormitory and live in Song Jong-ki's house in Seocho-gu. Song Jong-hyuk invites Kim Tae-yeon to dinner to thank her for her help while wanting to learn more about the past. Kim Taeyeon said that she was not familiar with him and could not do anything about it. Deeply disappointed, Song Jong-hyuk didn't know where to look for memories. Song Hyuk suggested that he try his luck at ** company.

Kim Taeyeon suddenly had a stomach problem while practicing at the ** company, and by mistake dialed Song Jong-hyuk's mobile phone, Song Jong-hyuk forcibly entered, and Taeyeon was sent to the hospital.

Song Jong-hyuk, who was waiting in a café near the ** company, met Choi Min-ho of SHINEE by chance, and learned from him the reason why he left the ** company that year. In 2007, Song Jong-hyuk was preparing to debut as a shinee, but he was anonymously reported for playing with the feelings of female trainees and was kicked out of the company by the top management, so that he broke off his dream.

Song Jong Hyuk, who learned the truth, was disheartened, and it coincided with Girls' Generation to start a concert tour in Japan, and in order to thank Song Jong Hyuk for saving herself, Kim Tae-yeon invited Song Jong Hyuk to watch. Song Jong-hyuk, who decided to go out for a walk, readily agreed. Song Jong-hyuk met Lee Soon-gyu for the first time backstage at the concert and keenly felt that Lee Soon-gyu's attitude towards him was very abnormal. Song Jong-hyuk, who thought that he was still his own evil in the past, did not talk to Lee Soon-gyu, but ignored Lee Soon-gyu's sad eyes looking at him.

Song Jong-hyuk said goodbye after watching the rehearsal of his youth, and was secretly stuffed with a piece of paper by the assistant of Girls' Generation to meet him. Song Jong-hyuk, who was confused, went to the appointment on time and met Luo Yali, a friend from the trainee. Luo Yali expressed her gratitude to Song Jong-hyuk. Song Jong-hyuk told Na Ya-ri that she had amnesia and asked her what happened to her report back then. After hesitating, Luo Yali told Song Jong-hyuk that he was framed back then. Song Jong-hyuk let go of the burden in his heart.

Song Jong-hyuk watched a concert when he was a teenager and was stimulated by the songs sung by Lee Soon-gyu, and recovered part of his memory. He is determined to return to South Korea and reclaim his memories.
