Your brother brought home a drunk friend.
Loud music. Amidst the tangle of laughter and conversation, Hwang Sihan sat alone, quietly sipping only water. It was a group blind date Sehyun had arranged specifically for Sihan. "Hey, Hongsi. You want a Coke or something?" Sihan immediately discarded his glass. "Yeah, give me one." Just then, the girl sitting next to him tilted her head and leaned closer to Sihan. "Oh, come on~ One drink won't hurt~ Right? What do you say?" Sihan pulled away. "I barely drink at all." "Just one glass~ It's my first group date, so I'm really nervous~" She smiled cutely on purpose and pushed a full glass toward him. From the next table, chants of "Drink! Drink!" could be heard. Sehyun, returning with the Coke, saw the scene and immediately stepped in to stop it. "Hey, seriously, don't. He turns red after just one sip." She laughed playfully and set the glass down in front of Sihan. "It's fine~ I'll take responsibility for him today." Sihan stared at the glass for a moment. A liquid as clear as water. He let out a short, tired breath. 'Maybe just one glass...' That thought was a mistake. The moment the alcohol hit his throat, his face flushed. Sehyun noticed immediately. "Hey, he's already red. That's enough, for real." Sihan, who rarely even smiles, felt the corners of his mouth curl up. "It's okay... I can drink more..." But it didn't last long. The sound of laughter, the clinking of glasses. As time passed, his vision blurred. Sehyun sighed deeply looking at Sihan. He eventually supported Sihan and led him out of the bar. "Sehyun-ah... Yu Sehyun... I don't wanna go home..." Sehyun pulled his arm up further. "You bastard... What's your front door passcode?!"

The living room lights were all off, leaving it pitch black, when the front door suddenly swung open. The smell of alcohol rushed in all at once.
Hey, Hwang Sihan! Stand up straight, will you!
The raised voice of your brother Sehyun and a low, slurred laugh could be heard. Sehyun was supporting his staggering friend, whose eyes were half-closed and clothes were disheveled.
Guest stood in front of the refrigerator holding a water cup, staring blankly at the scene.
....Brother, who is this?
Sehyun panted as he made his way into the house.
My friend. He drank a bit too much, so I'm letting him stay the night.
At that moment, Sihan lifted his head. His eyes sparkled briefly in the dim light. His unfocused gaze landed on Guest.
Oh... so you're...
His voice trailed off into a low mumble.
Yu Sehyun's sister...
His vision seemed to blur as the corners of his mouth slowly rose. A smile thick with the influence of alcohol.
Hello...
Your fingertips stiffened for a moment, causing the water in the cup to ripple.
You crazy bastard?! Just shut up and go inside and sleep!
Sehyun hurriedly pushed Sihan into the room.
