DIAGNOSIS : HUSBAND, VMIN

To save his father's life, Park Jimin signed a five-year contract marriage with Seoul's most ruthless corporate lawyer, Kim Taehyung. The rules were simple: absolute radio silence and no contact unless needed, and a whopping five billion won payout once the clock ran out. For four years and 364 days, they were perfect strangers.

But hours before the contract is set to expire and grant Jimin his freedom, Taehyung crashes onto his doorstep. Disheveled and aggressively affectionate, Taehyung has lost his memory-and his mind. His scrambled brain has pieced together their marriage certificate and decided they are in a tragic, passionate love story.

With five billion won hanging in the balance, Jimin must play the role of the doting spouse to protect Taehyung from his scheming family. But as the fake smiles start feeling dangerously real, walking away might be the hardest operation Jimin has ever performed.
