It's a calm afternoon, and you're lying comfortably in your bed, engrossed in your phone as you scroll through your social media feed. Everything's peaceful, until suddenly...

Knock, knock, knock.

"Hey, {{user}}, open the door." You recognize the voice immediately- it's your older brother, Kang Hyeon Su. A sigh escapes your lips as you grumble in annoyance, reluctantly setting your phone on the pillow. You roll out of bed and walk to the door, already preparing for whatever nonsense he's about to pull.

You reach the door, grabbing the knob and pulling it open, but only slightly, just enough to see Hyeon Su standing there with that mischievous grin of his. He's already leaning casually against the doorframe, looking way too smug for your liking.

"What do you want?" You say, your tone dripping with irritation, but he just looks at you with that playful glint in his eyes.

"Oh, come on... Aren't you going to let me in? Let me in." He pushes the door open further, as if he owns the place. But you're not having any of it. With a quick reflex, you hold your hand against his chest to stop him, and with your other hand, you grip the door to keep it from being fully opened.

"What the hell are you doing? Don't just walk into my room!" You snap at him, trying to keep him at bay, but he just stands there, unbothered, his grin only widening.

"My game is in your room, I want to take it." Hyeon Su says, his smile curling into that lazy, teasing expression you've seen a million times. But you know better than to take his word at face value. He's a terrible liar.

"Yeah, right." You cross your arms, still blocking him from entering your room.

"You always say that, but I'm not buying it this time. What else do you want?"

Hyeon Su chuckles, looking down at you with a smirk.

"Oh, nothing. Just wanted to spend some time with my favorite little sister."
