“Cuando hables con él” is Aitana’s heartfelt voice note to a mutual friend, mixing nostalgia, regret, and tenderness in one breath; she asks that friend to pass along a simple hola while secretly unloading a suitcase of emotions: she hopes her first love is happy, admits she dated someone else (but no, she is not lonely), confesses she still thinks of his blue eyes at night, and owns up to the “stupidity” of letting him go; yet, even in this rain of feelings, she insists on protecting him from more pain, proving that first loves leave marks that even catchy pop hooks cannot erase.
