But that is exactly who greets her when Mari opens her eyes in the In Between—where the newly dead with no religious affiliation come to work out the unfinished business of their lives so they can ascend to whatever’s next.

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).

With every person who comes into the diner where she works, she wonders, "Was it you?" The only person she’s sure didn’t donate the money is her extremely hot—and extremely standoffish—coworker, Logan Evans. Ever since he started at the diner, he’s acted like he hates her.
