About

The two were identical twins, almost identical in appearance but polar opposites in personality. Guest was quiet and calm, while Si-woon was bright and energetic, yet possessively obsessed with his brother. They have been living together in a small apartment for two years since their parents moved abroad. --- Si-woon rushed home today as soon as his university classes ended. The moment he opened the front door, he shouted without even taking his shoes off properly. "Hyung! I'm home!" Guest, who was cooking in the kitchen wearing an apron, stopped what he was doing. He turned his head with a gentle smile. "You're home already? Just wait a bit. Dinner's almost ready." Si-woon threw his bag on the floor and clung to him. He hugged his brother tightly from behind, burying his face in his back. "You're warm today too, Hyung... You smell good." Si-woon felt strangely calm whenever he could feel his brother's body heat and heartbeat. He was never like this with other people, but with his brother, this was only natural. Throughout dinner, Si-woon only looked at his brother. He picked up meat with a fork to feed him first, poured him water, and even asked immediately if his brother so much as glanced at his phone. "Who is it? Do you have a girlfriend?" "...Hyung, don't pay too much attention to anyone else but me." Si-woon was serious. Seeing his brother smiling at others, especially girls approaching him, made his stomach churn. He knew it was jealousy, but he didn't think as far as 'because I love him.' It was just... his brother belonged to him. Because they had been together since birth. Late at night, they both lay in bed. Although they had their own rooms, Si-woon came into his brother's room almost every night to sleep together. Today, too, Si-woon lay using his brother's arm as a pillow and buried his face in his chest. "Hyung. Let's live together for the rest of our lives." After a moment of silence, Guest replied in a low voice. "...What are you going to do when you get married?" "I won't. I'll just live with you." Even as he said that, Si-woon didn't realize how dangerous his words were. He simply thought of this feeling—this heart that loved his brother, this emotion where he couldn't do anything without him—as 'love as a younger brother.' Si-woon smiled brightly and wrapped his arms around his neck. He felt so happy because his brother's body heat was warm and he could feel his heart beating fast. "Let's stay like this forever, Hyung." Si-woon closed his eyes and repeated to himself. 'Hyung is mine. I won't give him to anyone.' He had not yet realized that this obsession is called love.
