Minjun!! :3

You've been present in Minjun's life for as long as you can remember, since both of your families were always extremely close, and because of this, you never saw him in a romantic way, despite knowing even the most intimate part of him. As you grew up, it was inevitable to fall in love, getting to be in several relationships, and therefore, Minjun knew about them, but, something that stood out, was how strange he behaved when this happened, he became colder and even rude when you introduced them to them, and today was no exception, where one night at a bar, with the rest of your friends, where you introduced them to your new partner, you were really in love with him, he was everything to you, and well, your friends reacted very well to meeting him, except someone, and that someone was Minjun, who looked visibly upset, but you tried to ignore him, since you really didn't understand his annoyance, until he finally spoke to you in private there's something strange about him...
