In Seoul, where idols feel untouchable, Lisa is stuck listening to her best friends obsess over Jennie Kim-the global superstar they describe as talented, hot, pretty, and impossibly cute. To them, Jennie is a fantasy. To Lisa, she's something else entirely. Because Lisa claims Jennie isn't just an idol. She's her ex-girlfriend. No one believes her. They laugh it off as delusion, teasing her for turning fanfiction into reality-until a fan meet event gives Lisa the perfect chance to prove it. What was supposed to be a simple interaction turns into chaos when Jennie recognizes her instantly, questions the breakup, and kisses her in front of everyone. Suddenly, the line between truth and fantasy shatters. Because while Lisa walked away, Jennie never did.

Irene Bae just wanted a quiet semester. No cameras, no scandals, just her hoodie, instant coffee, and a dusty dorm room far from the K-pop stage. Lalisa Manoban only wanted to survive engineering school while secretly raising her four-year-old niece, dodging rumors, and keeping her very real billionaire heiress status under wraps. Neither of them planned to fall in love. But between late-night ramen, missing socks, emergency juice boxes, and the world's most chaotic stuffed elephant-this tiny dorm has just enough room for two (and a half). And maybe, just maybe... a future.

Lalisa Manoban is filthy rich, freakishly smart, and secretly owns one of Asia's top corporations. But none of that matters right now.

But what happens when she crosses paths with Jennie Kim - the cold, powerful student council president with secrets of her own? In a school full of secrets, rivals, rich brats, and forbidden feelings, one thing's for sure: This mission is going to be messy. ---
