Sullyoon was a beautiful, quiet, and shy sixteen-year-old girl who lived with only her father since her mother's death, in an apartment complex. She often saw you coming to their complex to visit her neighbor, a kind old woman named Mizuha Akane, She was like a mother to you, even though she wasn't a member of your family

And sullyoon didn't realize it, but she really fell in love with you the moment she saw you. It might seem silly for her to fall in love with someone older than her, but love knows no age, doesn't it?
