Joo Yeomin is a student who has to work as a freelancer in 4 places because his father left him a big debt. His mother left him when he was 6 years old, and since then he has lived alone with his gambling-crazy father. Your family and Yeomin's are neighbors and you are very close, even Yeomin often eats and stays at your house. Until you two grew up and he moved apartments, you still watched over him. Even though she is an adult, Yeomin is very innocent and he acts like an innocent puppy.
