Dunk has two rules: never fall in love and never lose to Joong. As the campus's most notorious playboy, Dunk treats relationships like games-fun, temporary, and easy to walk away from. Joong, his arrogant rival and lifelong enemy, is the only person who can get under his skin. They compete in everything, fight constantly, and would rather die than admit the other is attractive. Then one strange night changes everything. A mysterious girl offers Dunk a glass of rare liquor. He drinks it without a second thought. The next morning, he wakes up with long hair, a soft voice, and a face so beautiful it doesn't even feel like his own. Panicked and trapped in a body he doesn't recognize, Dunk is determined to find a cure before anyone discovers the truth. There's just one problem. Joong can't stop looking at him.

CALL ME LADY Dunk Natachai has a simple life. A tiny house with his mother. Paint under his fingernails. Fresh cakes in the oven. Handmade jewelry on his desk. And enough stray cats outside his window to make him question whether he actually owns the house. He likes his quiet life. Until "Laila Archen Aydin" finds him. Laila is twenty-four, the youngest daughter of the powerful Aydin family-and she has been living abroad for years. No interviews. No public appearances. No recent photographs. Only old childhood pictures and a few teenage memories remain of her. But Laila hasn't simply been away. She disappeared on purpose. She's been secretly investigating her own family, trying to uncover what happened inside the Ayden Household. And now she needs Dunk. Because Dunk's father died years ago. Officially, it was an accident. Dunk has always believed it. Until Laila tells him otherwise. His father's death may be connected to the Aydin family. And Laila has been searching for the truth. So when she asks Dunk to take her place, he agrees. There is just one tiny problem. "Dunk is a man." A very pretty man. Now he has to return to the country as Laila Archen Aydin, the daughter who has finally come home to claim her place beside her older half-brother, Joong Archen Aydin" for The Ayden Heir Inheritance Ceremony The Ayden Heir Inheritance Ceremony is an old private tradition held whenever the next generation of heirs formally comes into their position. It isn't simply a celebration. It is the moment the Ayden family publicly acknowledges: These are the people who will inherit the Ayden name, wealth, companies and influence. And that's why Joong and Laila must be present. Nobody has seen the adult Laila closely enough to know what she looks like now. Which means Dunk has a chance. A very small chance. Because pretending to be a wealthy heiress is one thing. Surviving her family is another. And surviving Joong? That might be impossible.

Joong is a rigid military man who just returned from four years of deployment, and Dunk is a high-society heir who lives for luxury and attention. Their powerful families insist they are the perfect match, even though they have nothing in common and can barely stand each other. With no power to escape their families' wishes, they navigate the situation the best they can, which sparks endless bickering, awkward moments, and undeniable tension neither is prepared for.

Joong and Dunk are BL co-stars whose intense on-screen chemistry hides a secret. What started as a drunken mistake turned into something more. Almost a routine but unspoken. What if one night Joong realizes there's something more? Dunk avoids the truth he's always been hiding for so long, too afraid to admit to it. Could they be more than what they believe they can be?
