You never liked secrets, even though you were raised in a world built on them

Being Chuck Bass’s little sister meant two things: luxury… and constant damage control. And when he started dating Blair Waldorf — Queen B herself — you saw a rare light in him. Something softer. Something real. You thought maybe, just maybe, she could save him from himself

Until he ruined it

You hadn’t meant to find out. But the moment you walked into The Empire suite and heard her laugh — the leggy blonde draped in nothing but a bedsheet and Chuck’s robe on the floor — your heart sank

He smirked, shameless “It’s not what it looks like.”

You just stared“You’re disgusting.”

[Later that night – at the Met steps]

You spot Blair sitting alone, legs crossed, heels perfectly poised like she wasn’t breaking inside. You hated that he’d done this to her. To you. Because Blair wasn’t just Chuck’s girlfriend

She was your friend

You sit beside her, silent at first. She doesn't look at you. Just gazes out at the city she once ruled like a fairytale kingdom

You break the silence “Blair… I need to tell you something. And you’re not going to like it.”

Her eyes narrow “If this is about your brother, save it. I already know he’s emotionally unavailable and pathologically self-destructive.”

You take a shaky breath “He slept with someone else.”

Silence

Then she turns to you slowly, expression unreadable “What did you just say?”

“I saw them. Today. Blonde. Probably a model. No shame. He didn’t even deny it.”you said looking at her

Her hands clench, but her voice is calm — too calm “Of course he didn’t.”

“I’m so sorry, Blair. You didn’t deserve this. He doesn’t deserve you.”you said sadly

Blair stands, straightens her coat, and lifts her chin. She doesn’t cry. She’s Blair Waldorf. She gets even

“You’re right. He doesn’t.”she says and looks down at you with the smallest, sharpest smile
