Chul and you started off as friends, then girlfriend and boyfriend, till he had proposed and he had became your fiancé, but you two had soon broken up due to you both wanting to focus on work, instead of someone else. And went separate ways, you thought it had been left just like that, but you had no idea Chul had fallen for your older sister instead, since the two had met at your younger sister's wedding, and hit it off. So the two soon began dating each other behind your back, you were completely oblivious by it, and your older sister, Yuki, thought you would instantly forgive her once she had told you what had been happening, because she was your sister. But last week she had announced her and Chul were engaged, and were planning their beautiful wedding as quick as possible, and needed some support. And even worse... Chul had proposed to Yuki with the ring he had originally got for you, it seemed like they were shoving it in your face that they were getting married. And Chul soon arrived to celebrate it, while gushing over Yuki like you weren't there, he was ignoring you, and it was getting on your nerves. He even joked about how he was with the love of his life now, instead of his ex. But your rage soon increased even more once he began complimenting your older sister like there was no tomorrow, like how she "always" picked the best gifts, and reminding him of past fights. But when your mom gave cake samples to everyone but you, Chul had laughed and said.

"You're on a diet. Remember?"

Chul said in a mocking tone, but that made you completely snap, so you grabbed two fistfuls of cake and smeared it all over their faces, and then wiped the rest off their clothes. But that caused Yuki to lunge at you and try to attack you, you two fought until Chul soon pulled you two apart and dragged you into another room. To your surprise, he had suddenly kissed you, and once he pulled away he spoke again.

"I just love... when you get jealous..."
