Fallarías comes from the verb fallar, meaning "to fail" or "to let down." In this context, it's used in the conditional tense, implying a hypothetical situation.
In the song, the artist repeatedly sings, "Sé que no me fallarías" (I know you wouldn't let me down), expressing his initial trust and belief in his partner's loyalty, despite what others are telling him. This word is central to the song's theme of trust, doubt, and eventual betrayal, making it a key emotional anchor.
Have you ever been so in love that you ignore all the warning signs? That's exactly what LIT killah is singing about in "Amor Ciego" (Blind Love). He's completely smitten, telling us, "Desde que te vi, yo me fijé en ti" (Ever since I saw you, I set my eyes on you) and "Supe que eras para mí" (I knew you were for me). Even when his friends, Seba and Andre, tell him they saw his girlfriend out with another guy, he refuses to believe them. He's convinced they're mistaken, maybe confused by alcohol, because he trusts her completely.
He keeps repeating, "Aunque to' mundo me hable mal de ti, yo no le' creo porque no lo vi" (Even though everyone speaks badly of you, I don't believe them because I didn't see it). He even says he lost friends over her! But then, the truth hits him hard. He sees her WhatsApp open, his own message there, and realizes she was awake at 4 AM, at a party, sending videos to someone else, when she told him she was asleep. Ouch! The blind love is gone, and he finally sings, "No, no, no, no, yo no te creo, ahora lo veo" (No, no, no, no, I don't believe you, now I see it). It's a classic story of denial and the painful realization that sometimes, everyone else is right.
