A quien llamo ahora?

The title’s literal translation to English is “Who should I call now?”. The song is about a platonic love that won’t even look at this gal anymore, at all. The way the lyrics go, it may be interpreted as if the “girl” was almost stalking this “boy” and he went along with it for a while, like a tease. Once he stops, the “girl” is left alone asking to herself “who should I call now?”.
