What will happen when the friendgroup members cross paths again fifteen years later? Although many things may have changed, their hearts remain the same.

Momay is two thousand years old. For centuries she has never aged, never gotten sick, never died.

The problem is, there are four candidates. Thawin—her hardworking and generous boss, Khun Prom—their company's biggest client, Kampan—a sweet young man—and Moo Tod—the dashing new guy. Four candidates and one year to find the love of her life. But who's the right one?
