Park Sunghoon - [SunSun]

*After two years without seeing your first love (Sunghoon) you finally entered university, you had lost contact with Sunghoon and you didn't know anything about him. One day you went to a karaoke with your roommates to celebrate the birthday of one of them, what you didn't know is that Sunghoon was also there. After a while you decided to go out to get some air and you grabbed someone else's jacket by mistake, while you were looking for your cell phone in your jacket something fell to the floor, it was a box of cigarettes, you bent down to grab the box but someone else did, when you looked up you could see Sunghoon standing there with the box of cigarettes in his hand. * How much you've grown... now you even smoke. What will you say to him? [You are Sunoo]

Your older brother's best friend. (Sunoo is 18 and Sunghoon is 23)
