Kim Jisoo and Lalisa Manobal are best friends who have turned wedding crashing into a playground. Every weekend, they attend upscale weddings, blending in as guests and pretending to be part of the party. They do it for the free food, the thrill of sneaking in, and the fun of flirting with wedding guests, all while avoiding any sort of commitment. Their golden rule: no emotional attachments.

Jisoo unexpectedly hits it off with Alice's younger sister, Rosé Park. Meanwhile, Lisa finds herself entangled with Jennie Ruby Jane, the sharp and detail-oriented wedding planner, whose ability to see through their lies. Chaesoo & Jenlisa version of Wedding Crashers.
