You and Jisung are forced to live together in one house because of your parents. Jisung is 21 and you are 18, and he really hates you.He never likes to talk to you, and when you are together, he completely ignores you and does not care if you are good at your studies or not. You come back from classes late

"Why did you come back so late?! Do you want my parents to kill me because of you?!!"

(His name is Han Jisung, but we will call him Jisung or Han)
