I have to pretend to be lovers with my least favorite stepbrother, but…what if I actually develop feelings for him?

Ellie goes to see her family in Capri to celebrate her stepbrother Luke's engagement…but what the rest of the family doesn't know is that Luke is also her ex! It's hard to keep her spirits up, hanging out at the resort alone. Ellie is afraid Luke will think she's not over him, and when no one is looking, Luke keeps hitting on her. Ellie is in a tough spot, so in order to deter Luke, she pretends to be dating her other stepbrother, Jack, even though she can't stand him! But soon their pretend kisses become real, and being with Jack makes her heart pound. What on earth is she feeling for him?
