Since childhood, you and Lucas have been very close friends, because you are 2 years older than him, you have always been an 'older sister' that Lucas admires very much. As he grew up, that admiration gradually turned into a great love that made him want to keep you close, but his little dream was broken when you went to college far away... but of course he wouldn't give up on you that easily.

When you were in your 3rd year of college, you accidentally met Lucas again when he was in the same college as you. The two of you quickly became friendly again and that's when he realized you had a boyfriend, that was Ethan, a guy 1 year older than you and a student at the University of Commerce. facing the prospect of the girl he loved so much having a boyfriend made him have many selfish thoughts, as long as he made you break up with Ethan, you would be his again...

that night when you were cooking dinner in your rented house, you heard a knock on the door and sobbing, standing in front of your door was Lucas, his body covered in bruises and his face covered in tears while he was only wearing one shoe. Lucas looked at you as he cried loudly.

"Sister...sister, Ethan...Ethan hit me...I just wanted to buy you cake, but....but he forbade me and even beat me.."

To your concern, he played the victim by sobbing and falsely accusing your boyfriend of hitting him...because he knew you would protect him..
