A spin-off to the New York Times best-selling Once Upon a K-Prom, a K-pop idol and an up-and-coming K-drama star must fake date in this fresh and funny romcom that Korean pop culture fans will absolutely swoon over!

Moon Minseok—or Moonster as this WDB fans know him—wasn’t born to lead. Even as part of the world’s most popular K-Pop group, he found comfort in his role as the jokester, the sidekick, the unserious one (with the cutest smile). But now WDB is drowning in dating scandals, and it’s time for Moonster to take charge of the group's image.

Shin Hyeri has been dealing with some scandals of her own. An up-and-coming K-Drama actress, she’s been labeled a “nepo baby” (with a famous idol as a big brother) and now, a bully (which couldn’t be further from the truth). Desperate to show the world that she’s earned her spot, Hyeri is determined not to let her rising star crash and burn.

When these two childhood enemies get caught up in yet another scandal while co-hosting a K-Pop festival, there’s only one solution that will save both of their reputations: appear on one of Korea’s most popular variety shows, Our Celebrity Marriage (where celebrities pretend to get married and compete in ‘newlywed’ challenges).

The plan is simple—pretend to get along, win back the fans, then go their separate ways. But what happens when a fake marriage leads to real feelings? Will Moonster and Hyeri bow to the pressures of their famous realities, or will they decide their love is something worth fighting for?
