“+” is a heartfelt arithmetic of love. Aitana and Colombian duo Cali y El Dandee sing from the raw moment when two people realize their first big romance is slipping away. They fight the clock, beg for a plot twist, and try to add (“más”) kisses while life keeps subtracting (“menos”) moments together. Math becomes poetry: February hurts extra because it once marked an anniversary, memories pile up like numbers, and even an entire alphabet feels too small to describe the loss. The singers cling to every sum of shared laughter and every product of shared dreams, refusing to accept that the answer might already be zero.
Despite the upbeat Latin-pop beat, the lyrics feel like a late-night diary entry filled with crossed-out plans and endless “te extraño.” The song captures that universal question after a breakup: where do you store a love that no longer has a home? It is a bittersweet reminder that first loves can fade, yet the equations they leave on our hearts remain unforgettable—and sometimes impossible to solve.
