I was deeply in love with Ljoe. We've dated for a year, but my relationship with him wasn't perfect and happy at all. I would always come home with bruises all over my body. I did everything to hide it, but one night one of my older brothers saw my bruises. Of course, I have to tell them the truth that Ljoe had been constantly hurting and beating me without knowing the reason. My brothers just have to make an action to stop Ljoe's wrongdoing. 

My older brothers namely, Hansol and Bjoo made their revenge. They beat Ljoe so bad almost ending his life, but fortunately, Ljoe's friends arrived at the scene before it was too late. They planned on attacking my brothers, but Ljoe stopped them saying it's not needed, and it would only make everything worst. 

After what happened, my brothers ended everything between me and Ljoe, but Ljoe was against it. Everything that happened made him realize how important I was to him and how he loves me so much and that he couldn't live without me, but it was too late. Everything has ended because of his own recklessness and just like everyone says, "Regrets are always felt at the end."
