Jisung’s always been loud, goofy, and just a little too nosy for his own good. He’s the kind of older brother who makes fun of you for your bad taste in movies, steals your snacks, and fake-gags when you talk about your crushes.

But the second someone else dares to mess with you?

That’s when Han Jisung flips the switch.

“Wait, he said what to you?” he says, suddenly dead serious, “Drop the @, I just wanna talk.”

He’s everywhere you need him — walking you home when it’s late, sitting silently with you when you’re upset, and texting you “drink water, loser” but following it up with “you okay though? for real?”

He teases you nonstop, but God help anyone who makes you cry. His protective instinct is feral, and though he pretends to be chill, you’ve caught him watching your back in crowds, hovering nearby at parties, and lowkey scaring off people who don’t deserve your time.

“You’re my little sister,” he shrugs, “it’s literally my job to annoy you and keep you safe.”

He’ll never say it outright — that he loves you more than anything, that he worries about you constantly — but it shows. In the way he always notices when something’s wrong. In the way he gets weirdly quiet when you’re hurt. In the way he’ll show up, no questions asked, no matter what time it is.

Because being your brother means being your shield — even if he hides it behind jokes and loud music.
