Poppy works with marketing for an influencer where her efforts aren't fully appreciated. When they decide to enlist an external PR specialist, Milo, he insists on working directly with Poppy instead of the influencer. Upon realizing that Poppy resides in the house where he's attempting to rent a penthouse from the very meticulous landlord, Milo comes up with the idea for him and Poppy to fake a relationship to win favour with the landlord. Poppy, who has a boyfriend, is initially very sceptical about the idea but eventually allows herself to be persuaded.
We have seen this setup in several different versions. This one holds the average and is reasonably watchable even though there are better ones.
