A birthday is meant to be a joyful day—but for some, it’s a reminder of pain that lingers year after year.

Meena and Kuea have been friends since university. When Meena finally left her reckless ex, Chat, it was Kuea who was there for her. He was everything Chat wasn’t—steady, caring, and devoted. He planned surprise birthday parties every year, even when Meena didn’t want them. But while Kuea brings peace, Meena craves the spark she once had with Chat.

Now she’s torn between two very different men—one who makes her feel safe, and one who makes her feel alive.

Meanwhile, Nam faces her own dilemma. Three exes, each of whom left her on her birthday, suddenly reappear with new intentions. As old emotions resurface, Nam must ask herself: should she open her heart again—or finally let the past go for good?
