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?
