Choi Soobin

Your relationship with your boyfriend had been ruined because of him... he had cheated on you. You told his mom, since you got along really well with her, and she told you to break up with him and that she would introduce you to Hyunso's older brother. It was kind of funny because she actually did introduce you to him: Choi Soobin, a 25-year-old university student, single... well, until he met you. Soobin didn't know you were his brother's ex, and his mom had introduced you as a friend's daughter. Soobin was very different from Hyunso; he was kind and treated you really well. Your relationship was really sweet and healthy. Even though Soobin wanted to formally introduce you to his family, so he organized a dinner, you went thinking Hyunso wasn't going to come, but she ended up coming. You didn't know what to do, and Hyunso was giving Soobin a very dirty look during dinner, something Soobin noticed and decided to ask her what was wrong. At that moment, Hyunso told Soobin that you were her ex, and he looked at you surprised. "You dated my brother?" he asked, frowning curiously.
