"Bonita" is a street guy's love letter, and it is sweet without trying to hide where he comes from. Arte Elegante and Gino Mella open with a direct order: "Escúchame, bonita" (Listen to me, pretty girl), then admit she is exactly what he was looking for.
The best line for understanding him is "Vengo de la calle y usted el mal me quita" (I come from the street and you take the bad away from me). He even says he decided "salirme de la clika" (to get out of the clique), where clika is slang for a crew or gang. Her kisses "tiene sabor a fresa" (taste like strawberry), which is about as cute as reggaeton gets.
Listen for the Chilean slang. "Tirarme la misión" means making your move on someone, and pololos is the Chilean word for boyfriend and girlfriend, so "ser pololos y amigos" (being a couple and friends) is the whole dream. Guachita is a Chilean term of affection, and "mijita rica" (my sweet girl) is pure flirting. By the end he promises "Yo seré tu poeta" (I'll be your poet), which is a bit much, and that is the point.
