A Korean romantic drama adapted from a Japanese novel, this 2025 film follows a high school girl with anterograde amnesia who wakes each day with no memory of the day before, and the shy classmate who quietly falls for her anyway. The premise demands daily sincerity rather than grand gestures, which is about as traditional a romantic framework as the genre offers. No social critique, no identity politics, and no ideological subtext compete for attention. The family backgrounds are present but peripheral. The film's entire emotional architecture rests on heterosexual teen love and personal devotion under impossible conditions, which is what pulls the label toward Leans Traditional.
