Aguanto comes from the verb aguantar, which means 'to endure', 'to tolerate', or 'to bear'. It's a versatile word that expresses a struggle or a limit.
In the song, the artist sings, "Ya no aguanto, tengo que ser fuerte" (I can't take it anymore, I have to be strong). This phrase immediately sets a tone of emotional distress and resilience, making aguanto a key word to understand the song's central theme of enduring heartbreak.
"Traes Mi Corazón" is about loving someone who brings you both comfort and pain at the same time. The singer opens by admitting they're worn out and trying to stay strong, weighed down by sadness they can't shake.
The chorus captures the conflict at the heart of the song: they want to walk away from the relationship, but their partner still holds their heart, so leaving isn't that simple. They worry about a future where this person isn't around anymore, even while doubting whether their own feelings are returned.
By the end, the singer looks inward, wondering what it is about them that keeps this pattern going, and decides that saying goodbye might be the healthiest choice, even if it's a hard one to make.
