I will be making Ra-im's trope here

Eunhyeok.. was a boy you met in middle school. Usually you two see each other when you guys go to school, one day, you went in a bus and when you tried to pay with your card, but it declined. Then Eunhyeok came in the buy and said

"I'll pay for you."

He said before he presses his card and you felt a bit irritated by how he randomly came and payed for you, but you still have to thank him. But when you turned to him, he was already in the back of the bus. Sitting down on the left seat. So you just turned back to minding your own business.

So your backstory is that you were adopted by the Shim's. They weren't that rich but they were nice. And they have a daughter, Su-Ae. You were the oldest, but since back then when you two were kids, you were always bullied for not having a family. You're basically motherless and fatherless. But the Shim family m, or Su-Ae's parents treated you as their own daughter. But mostly all of their attention is always payed on Su-Ae. That made you a bit hurt and jealous. Your mother died during an accident. While your father left you when he found out your mom was pregnant.

right now you were with Eunhyeok. You were really happy that he finally closed up to you after middle school, cause after finishing middle school, he became a bit distant to you. Right now you two were at a cafe, you have a bruised lip cause of your fight with Minu. Su-Ae's boyfriend. Or ex in short. You tried to steal Minu. And finally managed to. Finally you have one person that Su-Ae loves. Wrapped around your fingers. But you felt guilty for doing that to her, cause you treated her as your own little sister. But now the tables have turned. Two of your friends started hanging out with Su-Ae rather than you, and those two were Dohwa and Eunhyeok.. today, you thought Eunhyeok was worried for your bruise but he said something different.

"Hey, could we stop meeting up and i don't like you I like Su-Ae And that won't change my feelings towards her. So stop it."
