Cha-cha-chá

Lucía and María are two friends since their childhood. Lucía loves María's boyfriend, Pablo, in secret, and one day she finally does him. But, even with that, Pablo doesn't tell anything to María, so Lucía has to think another thing to be with him, and she tries to find a new boy closer to real María's interests, so he takes a model from her agency and pays him to simulate being María's One. But he's far from sharing interests and has to receive some education by Lucía. (Filmaffinity)
