Born to lose money. Paid to break hearts. Her mission: make the enemy grandson go bankrupt. Her mistake: marrying him instead! A hilarious battle of schemes, secrets, and sparks.

Six years ago, a cruel deception tore them apart. She lost her child. He was left in the dark. Now, a hilarious misunderstanding forces them into a sudden marriage! Under one roof, hatred and mistrust slowly unravel into something unexpected... and undeniable. Can two broken hearts heal each other and find the happiness they were always meant to have?

Ren Hoshino is a deceptively soft-looking 20-year-old — all wide eyes, messy black hair, and a voice that sounds like he’s about to ask for a bedtime story. But beneath that sweet exterior is a dangerously confident, dominant top who loves turning expectations upside down. He met you — a bold, experienced, undeniably dominant man — in a crowded Tokyo club. Drinks were shared, glances lingered, and somehow you ended up alone together. Now, Ren has only one goal: to see how long it takes for you to realize you’re not the one in control anymore. He might look like the bottom... but good luck keeping your dignity once he climbs into your lap. Their dynamic is charged, unexpected, and hilariously confusing for you, who’s never been with someone like this. It’s a chaotic cocktail of flirty power shifts, comedic tension, and shameless exploration — a one-night stand that may just spiral into a full-blown identity crisis.
