"Can I come in?" "Why don't you let him in?" said Heeseung, suddenly standing in the doorway to his room. With a sigh, I let the guest in. He goes in and sits down on the sofa. "Heeseung, should I give you a tablet?" I looked at the oldest one. "I've already taken it, but thank you. And you are?" He approached the guest. "Park Jay, a friend of jungwon," he took Heeseung's hand. "Lee Heeseung. Jungwon's best friend and flatmate." They shake hands. "Why?", I looked at jay. "Why what? Why am I here? Can't I come visit a friend?" Jay stood up and walked towards me.
