Lovely Heart(2019)

Lovely Heart is a romantic comedy series following Aina Endou, a spirited high school student who masks her rebellious nature behind a cheerful exterior. She breaks school rules with ease—wearing her hair dishevelled, sneaking sweets into class, and casually nicknaming her teachers. Her homeroom teacher, Tanaka, attempts to correct her behaviour by asking her to stay after school. Alone in the classroom, Aina's true personality emerges as she flirts boldly with him, blurring the line between student and teacher. The series explores their unexpected connection as Aina pursues Tanaka with playful persistence, creating a tension-filled dynamic that challenges both their positions and feelings.
