Fair Play (Netflix)

Emily (Phoebe Dynevor) and Luke (Alden Ehrenreich) are madly in love, but because they both work for the same financial company, they pretend to have a platonic relationship at their firm, One Crest Capital, where employee intimacy is a violation of company policy. Shortly after Luke asks Emily to marry him and she happily accepts, she's given a promotion that they both thought would go to Luke.

When co-workers snark that she must have gotten the promotion by sleeping with their older boss (Eddie Marsan), Luke begins to wonder, especially because her new position seems to require her to go out at all hours of the night and attend after-work drink sessions with colleagues at bars, which puts a strain on their relationship.
