Being the best in your field can be a headache sometimes. Or maybe we should call it a Heartache. Lee Dami, the star wedding planner from Elite Organizing Agency, is stuck in a tornado of nostalgia and resurfacing heartache. The reason being her ex. The break up was as hurtful as catching them making out. But what twisted the knife in her back, was that they loved each other. And so, she leaves Korea. After four years, she's back and she's thriving. But it comes crashing down when she is to plan the wedding of her ex boyfriend Kim Namjoon to her ex best friend Ahn Taehi. But thankfully, she has one ray on sunshine in her life, yet. Min Yoongi. Her old best friend with whom she had 'lost' contact after moving abroad. And now that she's right back where she had left everything, will they stick together this time? Or will it all end just the way it had four years ago? With Dami leaving Korea and Yoongi standing all alone in the crowds of the airport once again?
