He hopes the confession will end the harassment, but Seo-yoon accepts immediately and records him as her boyfriend, forcing him to deal with the consequences of his lie. What starts as deception gradually becomes genuine as he spends time with her.

Seo-yoon has anterograde amnesia caused by a traffic accident. Each morning her memory resets to the day of the accident, meaning she cannot form new long-term memories. She relies entirely on written notes, photographs, and recordings to understand her life, relationships, and daily activities. Every day is essentially a fresh start.

Foreshadowing: The opening scene shows her recording a quiet moment with her mother, establishing her need to preserve memories.

After Jae-won dies from his worsening heart condition, Ji-min fulfills his final request to spare Seo-yoon the trauma of repeatedly reliving the loss. Since Seo-yoon's memory resets each day, she would have to grieve him anew every morning, which would be emotionally devastating. Ji-min hides all records of him, her diary, phone, and shared memories, so she never has to experience that pain.

Foreshadowing: Jae-won's hidden heart condition is revealed before his sudden decline.

• ji-min
• memory erasure
• protect
• grief

Seo-yoon forgets Jae-won entirely because Ji-min systematically removes all traces of him from her life. Ji-min hides her diary, deletes records from her phone, and removes any evidence of their relationship. Without these external memory aids, Seo-yoon has no way to remember Jae-won since her condition prevents her from forming new memories that persist between days.

Foreshadowing: The bus incident earlier already demonstrated how fragile their bond is when she cannot recognize him.

• forget
• memory erase
• records
• diary

Seo-yoon accepts immediately because she has no memory of previous interactions with him. Due to her amnesia, every new day is like meeting someone for the first time. When Jae-won confesses, she has no reason to doubt his sincerity and decides to give the relationship a chance, documenting everything about him in her notes for future reference.

Foreshadowing: Her first encounter with Jae-won on the bus happens before the false confession, establishing initial attraction.

Jae-won dies from a worsening heart condition that was hidden from Seo-yoon throughout their relationship. His health deteriorates suddenly, leading to his death and leaving behind his grieving father Kim Sang-hyeon.

Seo-yoon learns the truth when Ji-min finally confesses after her condition begins to improve. Ji-min returns all the hidden records, her diary, phone, and shared memories.

Foreshadowing: The mysterious drawings appear throughout the period when she has forgotten Jae-won.

• discover truth
• drawings
• diary
• ji-min confession

The drawings represent Jae-won, whom Seo-yoon has forgotten due to Ji-min's memory erasure. Despite losing all explicit records of him, Seo-yoon continues drawing him unconsciously, suggesting her emotional memory persists even when her explicit memories are erased. These sketches become the key clue that leads Ji-min to finally reveal the truth.

Foreshadowing: The drawings accumulate over time in her room, unnoticed until Ji-min discovers them.

Seo-yoon desperately avoids falling asleep on the bus because it means she loses time and context. When she does fall asleep and wakes, she cannot recognize Jae-won, her external memory references are not immediately accessible.

The incident reveals how fragile their relationship is when she cannot access her notes.

Foreshadowing: The importance of staying awake is established early as a coping mechanism for her condition.

• bus sleep
• panic

Seo-yoon's condition gradually improves, allowing her to form memories that persist beyond a single day. This improvement enables her to eventually process the truth about Jae-won when Ji-min confesses.

Foreshadowing: The timeline notes her condition slowly beginning to improve before the truth is revealed.
