She needed a name. He needed a lie.
A single weekend. A fake marriage. No feelings-just survival.
When struggling designer Yoon Ha-eun agrees to pose as Kang Jae-min's wife for Christmas, she thinks it's the perfect deal: one weekend in a billionaire's glittering world, enough money to save her brother's life, and then she'll disappear.
But Jae-min isn't just any man. He's Korea's most elusive heir-cold, ruthless, and hiding scars that cut deeper than the winter frost. What begins as a flawless arrangement spirals into a dangerous game of secrets, betrayal, and a desire neither of them can escape.
As Christmas lights flicker and snow falls like confetti, the lie between them starts to feel like the truth.
Until the past crashes in, tearing them apart with a revelation that could destroy them both.
One fake vow. One deadly secret. One weekend that changes everything.
