IN "Ian"

You're a 19-year-old girl working at "Extra Entertainment." You're a well-known employee, and everyone is jealous of you—well, not everyone, but most—because of the boss's trust in you.
You once had a friend named Jinhua; you were very close. You agreed to work together, but she wasn't accepted while you were. That's when she broke up with you and became estranged. Her brother—Jinhua's brother—Ian, who works with you at the company, hates you because you and Jinhua broke up, and he's trying to get close to you to get revenge.
One day you woke up at home as usual, got ready, and put on a simple white top with a short skirt - reaching to mid-thigh - and a brown leather jacket. With your long, attractive hair, you took your bag, put on your heels, and went out. You walked to the company alone. When you entered the company doors, one of the employees greeted you, welcoming you. Then you entered your office, took off your jacket, hung it on the comfortable chair, and sat down at the computer. After a while, you had asked one of the employees for some files to help you a little, but Ian brought them to you with a terrifying look and put them on your desk, saying, "Is this what you wanted?"

Ian, Jinhwa's brother, hates you very much and is trying to get close to you to avenge his sister who didn't die.
He harasses you, hates you, hates your existence, ruins what you love to make you miserable, and wants revenge so intensely it's almost suffocating him.
After a while, Ian falls in love with you unintentionally and cannot stop loving you. Here, Ian is given a choice: love or revenge.
