When your ex gets engaged to your cousin, what do you do? Hire your worst enemy to pretend to be your boyfriend, obviously. Twenty-three-year-old Isla Navarro is determined to win the breakup—until she realizes her ex is marrying into her own family. To survive the upcoming wedding chaos, she impulsively bribes the only guy who might hate her more than she hates him: Liam Reyes, the grumpy law student she accidentally got suspended in college. Liam wants nothing to do with Isla—or her drama—but he does need quick cash and a fake girlfriend of his own to impress a scholarship board. Begrudgingly, they strike a deal: pretend to be madly in love for one week. Easy, right? Wrong. Because somewhere between fake kisses, accidental sleepovers, jealous exes, and an overinvested Filipino tita brigade, lines start to blur—and hate starts to look a lot like love.
