Solji has a crush on Yerin. She musters the courage to confess her feelings, but Yerin rejects her, leaving Solji the subject of ridicule among her peers. Amid the turmoil, Solji opens up to her new math tutor, Ms. Jina. However, she soon discovers that Yerin is also Ms. Jina’s student—and seems to be closer to her than Solji is. Consumed by jealousy, Solji ends up confronting Yerin.

Solji sends a letter to Yerin asking, "Will you be my girlfriend?" The crumpled letter leaves Yerin describing her friend's feelings as awkward, causing emotional wounds. Like the name games taught by her tutor, relationships aren't easily untangled for the girl, and the film does not pretend that conflicts are simple to resolve. The nuance of the word 'queer' has evolved significantly in Korean cinema. Although the use of music is minimal, the way it is employed delicately portrays the child's emotions. The soft embrace of piano notes when the girl struggles and the theme song sung by Kim Hasol, who plays Solji, convey warmth and tenderness. (Lee Yongcheol)
