In a flashback to 2006, high schooler Jun-young learns why his mom had to raise him alone. Eul, also in high school, witnesses a terrible accident.

Jun-young's manager finds out about Eul's dire financial state and tells Jun-young, who tries not to be concerned but can't help thinking about her.

Eul visits Jun-young to discuss the documentary, but he changes his mind -- again. Ji-tae is dating Jeong-eun despite having no feelings for her.

Eul puts herself at risk of getting fired from the documentary crew. Later, she half-jokingly confesses her feelings to Hyeon-u.

With Jun-young and Eul making headlines, Jun-young is nowhere to be found. His management is frantically looking, but not even Eul knows where he is.

Jun-young's sudden change in attitude toward Eul has her convinced she made a mistake while drunk, but she can't remember what she did wrong.

Jun-young is intent on winning Eul's heart. He runs into Ji-tae while visiting Eul and begins to sense something suspicious about Ji-tae.

With everyone thinking Jun-young is dating Yu-na, Eul continues to shoot her documentary. Ji-tae urges his mom to tell Dad the truth about everything.

After a phone argument with his mom, Jun-young ditches the K-Pop Festival and spots Eul driving a van, speeding toward Choi Hyeon-jun.

Ji-tae asks his father to release Eul. Jun-young tells his mom about the things Choi Hyeon-jun did to Eul years ago and why he quit law school.

Jun-young plans to reclaim justice for Eul by exposing her dad's real killer. Jeong-eun gets extremely distraught when Ji-tae doesn't show up.

Eul is hurt by Jun-young's cold demeanor. Ji-tae's mother informs him that Jeong-eun will take over his director status, but he seems unconcerned.

Jeong-eun visits Jun-young to turn down his necklace gift but faces embarrassment. Ji-tae's mother hands Eul money, telling her to get away from Ji-tae.

Jun-young asks Jeong-eun to try and seduce him. Ji-tae tries to see Eul, but she won't meet him. Eul visits Jun-young to say goodbye.

Jun-young's doctor calls him to say Eul came by to ask about his condition. Eul wishes to rejoin the documentary team, but Jun-young pushes her away.

Angry that Jeong-eun got stood up by Ji-tae, her father intends to cut all ties with his family but learns that she is already dating someone else.

As Eul watches on, Jun-young completes his first -- which is also his last -- item on his bucket list. Soon after, the police arrive to arrest him.

Eul hands over the USB containing the video of Jeong-eun and Jun-young to Choi Hyeon-jun, asking him to return it before the scheduled airing.

The news reports a shocking video that mysteriously appeared on the internet. Meanwhile, Jun-young's memory loss is quickly worsening.
