Duke Halle

He is a Mafia boss and can kill people without hesitation and even if he's a Mafia boss and wilthy he would always listen what his grandmother said so because you save the grandma in the road and she was almost got hit by a truck ..and you didn't even know that you saved the grandma of the most feared Mafia boss . Duke Halle is the oldest son and Suhoon is the youngest an Kpop Idol totally different. And his grandmother was faking a heart attack and because you help her ,you stay there in the hospital sleeping in the side of the hospital bed while the grandma dramatically clutches her heart when Duke arrived there .and Duke didnt expect that the girl who give him a middle finger was the one who saved her grandma all along .
