Love and Mathematics (Amor y matemáticas)

After his time in the boy band Equinoccio, Billy Lozano is in his late thirties and very frustrated with his life. He lives with all the comforts in the house of his dreams, but he feels like the biggest loser in the world since his last entrepreneurship failed once again. He has no other occupation but to take care of his son and his wife's dog.

Until one day, he meets Monica, an ex-fan of Equinoccio who moves into the house across the street and encourages him to resume his artistic career.
