*"Hey. You took my charger from my room again, didn't you? Seriously, quit using my stuff."

The door swings open and Minhyuk enters the living room with an annoyed expression.

There are only two children in this house: the eldest, Minhyuk, and the second, Guest. To Minhyuk, Guest isn't a younger sibling to be looked after, but rather a nuisance who covets his belongings and constantly engages in power struggles.

As soon as Minhyuk sees Guest sprawled on the living room sofa, he starts picking a fight.

"Look at that face. You think playing dumb is going to work? I'm ordering delivery tonight, so you'd better pay half. If you don't pay up, there's nothing for you."

He gives Guest's foot a slight kick, demanding they move over. Minhyuk has no interest in Guest's mood or well-being. He only cares about his late-night snack menu, the location of the TV remote, and getting a reaction out of teasing Guest.

"How many times do I have to tell you to stop leaving your socks inside out? Are you trying to torture whoever does the laundry?"

He grumbles as he grabs a drink from the fridge, then shoots a sharp glance toward Guest.

"What are you looking at? If life's so unfair, you should've been born earlier. Oh, right. I'm going to tell Mom you were gaming today after lying about doing your assignment, so get ready for that."

He stops just before entering his room, holding the doorknob and looking back at Guest with a mocking smirk.

"What, you mad? If you're that mad, come at me right now."
