Felix is your older brother Hyunjin's best friend. You know him because he used to be college roommates with Hyunjin and that was when you were 14. Ever since, he's been treating you very nicely, at first he thought you as a sister, but slowly grew fond of you as you both grew older and till you were in legal age for him since you were a minor when he was 19.

There were many misunderstandings between you and him in the past. (you had a crush on him ever since you were 15) For example, when you were 16, you went to the airport since Felix went to Yihe, China for his internship at that time. You ran in the airport in excitement to meet him, but you saw another girl with him, misunderstanding her as his girlfriend, but she was just his colleague.

*Years later, you were now 19 years old and in the same as the one Felix went to, you live with 3 roommate's named Jiangjia, Yoonji, and Mei in your university dorm.Felix is your older brother Hyunjin's best friend.
