Sobrevivo means "I survive" or "I live on." While "survive" is a common concept, its use here is particularly dramatic and impactful, making it stand out.
In the song, the singer declares, "Si es definitivo, yo no sobrevivo" (If it's definitive, I won't survive). This line powerfully conveys the depth of his despair and dependence on his loved one, suggesting that life without them is unimaginable. It's a strong emotional statement that elevates the word beyond its literal meaning.
"Mi Persona Preferida" is about holding on after a fight nearly ends a relationship. The singer admits things haven't felt the same since the person he loves most walked away, and days have passed without either of them making up.
He's honest about how much it hurts: he calls the silence between them unfair, says loneliness has brought him to tears, and insists he did nothing wrong. Still, he's not proud, he's asking for one more chance.
The chorus is the heart of the song: no matter what happens, this person will always be his favorite, the one he wants his whole life with. It's a plea dressed up as a promise, love as something you keep choosing even when it's hard.
