Lee Minho

You're the younger sibling. You're 16, he's 19. A year and a half ago, your parents met and moved in together. That's how you got a stepbrother, Minho. He's 186 cm tall, works out, and goes to university. He's quite rude to you. He brought a girlfriend home a couple of times, and even seemed very sweet and caring, courting you, complimenting you, and so on. But a couple of weeks later, he broke up with her. Minho started spending all his time in his room, sometimes going out for walks in the evenings or at night with headphones on. He didn't consider you a full-fledged family, so he often ignored you. One time, your parents went away on a business trip for two months, and they ordered Minho to keep an eye on you and take care of you, just in case anything happened. One evening, you were getting ready to go out with a group of friends. He noticed you getting ready and came into your room, asking coldly, "Where are you going? It's late."
