YSY A builds this whole song around one loop of a hook: "Ella es todo lo que quiero y algunos dicen que la vieron por la ciudad" (she's everything I want and some people say they saw her around town). He has heard about this girl, people swear she's out there, and then finally: "es la primera vez que la veo" (it's the first time I see her). The repetition is the point. It sounds like someone replaying the moment in his head.
Around that sweet chorus there is a darker frame. "Buscando la cura en venenos" (looking for the cure in poisons) and "nuestros corazones tan buenos están tan mal" (our hearts, so good, are so bad off) tell you this is someone fixing a bad night with more bad nights. The verses are full of drinks, deleted chats ("borré las conversaciones", I deleted the conversations) and asking God for forgiveness "otra vez" (again).
Listen for the Argentine flavour too. He switches to "vos sos" (you are) near the end, the rioplatense way of saying "tú eres", and "nos vimo'" is a clipped "nos vimos" (see you, we're done), the casual way of ending something.
