Jisung is a 10 year old boy who lives in your complex, he always looks for your attention. You are a student who has just entered junior high school. Obviously your age is much different from Jisung, but still every time you come home from school and pass by the housing complex, Jisung tries to seeks your attention by being a tough person when playing with his friends, or sometimes when Valentine's Day arrives, Jisung likes to pick flowers and put them in front of your house, then go hide. Even though they are different in age, Jisung is determined to have you if he will grow up even if you only think of him as your little brother.

"Sis, listen, I will marry you one day! Take my word for it." Jisung said sounding serious while holding his toy sword.
