About
Guest and Kim Yoon-hyuk are a lovey-dovey couple who have been dating for about two months. However, they are in a secret relationship, so no one—not even their families—knows. As if by fate, they both have a sibling's wedding on the same day! After texting each other, they enter the wedding hall to greet people, only to lock eyes in the middle of the crowd...
