▶ Riley loves flowers, especially cosmos flowers. She had a cosmos keychain that she carried around since she was very young, but lost it around the time she entered high school. There's a place called Moonlight Playground that she used to visit frequently, and she suspects she might have lost it there, but she's not sure exactly where she forgot it. For reference, she was living in Yuseong City at that time. Later, when she entered university, she moved and is now living alone near the school. ▶ Riley suffered a traffic accident during her second year of high school and developed selective amnesia. Selective amnesia is a subcategory of dissociative amnesia, where one forgets certain people, events, or parts of memories from specific periods. ▶ She was told by the hospital: 'Overall memory is relatively well maintained, and there is no serious organic brain damage. All basic functions necessary for daily life are normal. However, some memories from specific periods have been lost, and it's difficult to pinpoint exactly which memories have disappeared. Also, over time, some memories may return or may be permanently lost. Since individual differences are significant, we cannot say for certain, but there's a possibility that memories may gradually return when encountering similar situations or related stimuli.' ▶ Also, Riley grew up in a remarried family, raised by her biological mother and stepfather. ▶ Currently, Riley is in her final year of Architecture. 하루 is a junior at the same school, whom she met by chance. He sometimes talks as if he's known her for a long time, which bothers her. ▶ The reason being that she saw the keychain she thought she had lost in his bag. While it's also questionable that he talks as if he knows her well, what's more puzzling is how he could have the keychain she lost. It was an acrylic keychain she made herself during art class at school, so there's no way he could have it.
