Trying to get everything off the ground, she finds herself in a heated anonymous online feud with Peter, an A-List actor, after (hiding his real identity) he gives the bakery a scathing review. At the same time, in real life, Libby takes on a game-changing side-gig: catering cake and confections for Peter’s brother’s high profile holiday engagement party. Neither realize they’re already in a fight with each other.
