One of the Main Characters/Love Interest

Kyun Yoon is the new transfer student who arrives at Jin's school and quickly gains popularity with the other kids. On her first day at school, she sees Jin getting beaten up and saves his life during the first few chapters of the series. Eventually, after saving Jin's life, she becomes the next target of Dongsoo. However, she is completely unaware of the twisted motives against her and it is up to Jin to protect her from his father's grasp at all costs. 

Kyun has also had her fair share of hardships. Unlike Jin, Kyun is very poor and has to care for her grandfather, who has dementia. She struggles with debt that her family had left her to deal with and her father tragically passed away. To get rid of this debt and the many other issues surrounding her, she is forced to take measures into her own hands and do things that put her at risk. Even through all this, she still manages to push on through the hardships that she goes through.

Kyun is a kind, sweet, and innocent girl, who has a bright personality that gives this dreary series a bit of light and serves as a direct contrast to Jin. She can also act a bit aloof at times and can be a little ditsy, which leads into some of the more comedic moments of the series.

Kyun's voice is somewhere inbetween high - medium range. Sweet and bubbly type of voice will do but can get rather solemn and humble when dealing with serious moments. She can also be a little bit sassy and fierce at certain times.
