"De Repente" paints the thrilling surprise of falling head-over-heels in love, following a narrator who is caught off guard by a gaze that melts his defenses and turns his whole world upside down. Abel Pintos uses images of a thousand eyes, words, and thoughts swirling around him to show just how overwhelming this new emotion feels, yet he admits that only one pair of eyes, one voice, one heart truly reaches him. The song moves between doubt and surrender: he considers escaping, longs for solitude, even calls his hope "a silliness," but every time he tries to pull away he is pulled back by an irresistible peace found in her kiss. With tender guitar lines and a folk warmth that mirrors the sincerity of his lyrics, the track celebrates wonder—encouraging us to protect that first spark of astonishment hasta el final (until the end).
