That's why he's gone to extremes to keep her at arms' length and to keep his hands to himself. Brooke Maccabe is focused on salvaging her struggling social influencer career. She doesn't want a boyfriend and if she did, it definitely wouldn't be her arch-nemesis Dean. After they end up in bed together on New Year's Eve, she tells herself it's a one-time thing. Until it becomes a two-time thing... and then a three-time thing. Before they know it, they're hooking up in secret on the regular.
