Kim Dahyun, the carefree and mischievous heir to Korea's largest tech conglomerate, lives a life full of brunches, luxury sneakers, and zero responsibilities. But when her family threatens to cut her off from the inheritance unless she "proves she's capable of protecting what's hers," she's thrown into a role she never expected: bodyguard to a princess.
Enter Minatozaki Sana - Japan's adored and elegant princess, recently relocated to Korea under a cultural exchange program. She's graceful in public, but behind closed doors? A whirlwind of curiosity, chaos, and secret snacks.
Their worlds clash immediately: Dahyun can't stand the royal rules, and Sana isn't impressed by Dahyun's "laid-back" professionalism (like: falling asleep during guard duty). But as the two navigate fake threats, nosy press, and secret rooftop escapes, they start to discover something unexpected- maybe the one thing Dahyun was always meant to protect... was Sana's heart.
Or maybe Sana is the one who'll help Dahyun earn her legacy- not through power, but through love.
When YN transfers to the city's most elite university, she expects quiet classes and a chance to finally outrun her past. What she doesn't expect is to be roomed with Chou Tzuyu, cold, ruthless, and a high-ranking member of the largest mafia in Korea. Everyone fears her. Everyone, except YN.
Because YN isn't the fragile girl she appears to be. She can fight, shoot, and survive, skills born from a life she never wanted. Skills she keeps hidden, along with the scars her father left behind.
Tzuyu swears she barely kills. YN swears she'll never fall in love. But between bloody turf wars, late-night fights, and whispered confessions in the dark... some promises are meant to be broken.
