Empreinte literally translates to "footprint" or "print," but it can also mean "impression" or "mark."
In this song, GIMS uses it to convey a deeper emotional impact. He sings, "Dans mon cœur, une empreinte" (In my heart, an impression/mark), suggesting that the person has left an indelible and lasting mark on his heart, rather than just a physical print. It's a beautiful way to express a profound emotional connection.
GIMS's "Bonita" is a passionate plea from someone who feels their love slipping away, yet is convinced the other person can't live without them. He's pouring his heart out, saying things like "J'te livre c'que j'ai sur le cœur, fais-moi confiance, je sais de quoi j'te parle" [I'm giving you what's on my heart, trust me, I know what I'm talking about]. He's watching her, noticing her change rooms, wondering if his presence bothers her, and seeing a fear in her eyes.
He keeps urging her, "Mírame, bonita / Regarde-moi comme l'autre fois / Quand on pensait ne jamais se revoir" [Look at me, beautiful / Look at me like that other time / When we thought we'd never see each other again]. It's like he's trying to remind her of a time when their connection was undeniable, before she started avoiding him and the flame they once shared began to fade. He's laid his heart in her hands, and he's desperate for her to just look at him again.
