5 Regras drops us right into the mind of someone who swears they have mastered the art of emotional self-defense. After being burned by past relationships, the narrator invents five iron-clad rules for staying cool: don’t pick up the phone on the first ring, disappear on a Friday night, never admit jealousy, keep the candles off the dinner table, and if an “I love you” slips out, run for cover with a plan B. The idea is simple: stay detached, stay safe.
Of course, love has other plans. The moment a new kiss arrives—“seu beijo é coisa de louco” (your kiss is crazy good)—all those carefully crafted strategies crumble. The song turns into a playful confession that theory is easy and practice is hard. By the chorus, the singer admits that every precaution has vanished from memory, because he is already head over heels. In short, “5 Regras” is a cheeky reminder that the heart often overrides even the most logical rulebook, proving that falling in love is delightfully uncontrollable.
