Soojin was 12 years old when she was knocked down by a girl in a park, she should get mad at the girl but there's a pull to that girl and she can't help herself, Yeh Shuhua is her name and she becomes the most important person in Soojin's life

Soojin had always been a very shy girl but Shuhua was the opposite of her, clumsy, talkative, loud, they were like yin and yang but somehow they clicked, despite the age difference the bond between them only increased over the years and according to her halmeoni the connection between them was something from past lives, past lives or not Soojin knows she shouldn't feel the way she does for Shuhua, she shouldn't spend her nights wondering what it would be like to kiss her best friend, she should be like every 17 year old girl in her class and have crush on kpop idols and oppas, Soojin then decided to bury these feelings inside her, Shuhua was too important for her to risk losing her because of a silly crush
