They were once inseparable-best friends, almost something more-until a single betrayal shattered everything.Years later, Luíza walks back into the last place she ever expected to be: the pediatric oncology wing, now as a volunteer nurse dedicated to helping children fight for their lives. What she didn't expect was to face the man she's spent years trying to forget.Bernardo, her ex-best friend, the boy who knew every corner of her heart, is now the supervisor in charge of every step she takes. Their reunion is anything but gentle. Sharp words. Wounded glances. A tension too heavy to ignore and too familiar to deny.When circumstances force them into a marriage of convenience, they sign a contract built on rules-no emotions, no slipping into old habits, no reopening wounds that never healed.But rules mean nothing when touch becomes temptation, when memories refuse to stay buried, and when two people who once dreamed of a shared future realize their story was never truly over.Because some loves don't end.Some loves linger.Some loves demand a second chance.
