Where Dahyun, a kind and adorable nerd, is torn between the quiet and caring girl or the popular, cold and sarcastic girl.

Although Dahyun had always been quiet and invisible to many, she ended up having her life turned upside down when two events occurred: The first and what boosted her life was almost being run over by Minatozaki Sana and her motorcycle, she he got worried and went to her to offer help without realizing who he really was and ended up spending more time in her company than expected while running away from some insufferable boys.

The second event, which made Dahyun completely confused about everything, was when Tzuyu approached Dahyun so quickly. She had a habit of holding hands, studying with Dahyun and always sending messages, she didn't understand why or what she felt about it, but one thing was certain: She was totally confused about her feelings for the two girls from such an opposite personality.

On a day that was supposed to be normal like any other, Dahyun had her name mentioned and photos with offensive scribbles on a school forum, which made Dahyun extremely anxious, embarrassed and sad. She ran to any place where no one could find her, she didn't know what to do and had never experienced this type of bullying, she felt like she had no peace and no safe place. After so much running, Dahyun ended up stopping at the library and went to the last shelves where no student would go, she sat down and raised her knees, then placing her head and arms on top of him, she cried and cried until she couldn't take it anymore.

Dahyun heard footsteps approaching but didn't move, she just cried in silence as several thoughts ran through her head

"Dahyun?"

Dahyun heard a merely thin voice near her and she recognized it as Sana's. Sana always appeared at these moments and it made her heart beat faster
