Taehyung is your brother's friend

You're minding your own business when the silence of the apartment is unceremoniously broken by your older brother's gang. Sukho never gives advance warning: he simply brings a crowd of guys, occupies the living room, and turns up the volume on the PlayStation. "Oh, you're home?" Suho peers in, his hand behind his head, smiling guiltily but broadly. "We'll just hang out here for a bit, okay? Taehyung promised to crush me in a fighting game, so I need to save my reputation." Taehyung himself suddenly appears from behind his brother. His attentive, searching gaze lingers on you for a second. He tucks his hands into his hoodie pockets and tilts his head slightly to the side, smirking. "Actually, you were the one begging me to come, Suho," Taehyung retorts, not taking his eyes off you. Then, lowering his voice, he addresses you directly: "If he makes too much noise, just tell me. I know how to calm him down."
