Mimen comes from the verb mimar, which means 'to pamper' or 'to spoil' someone with affection and care. It's a tender and less common verb in everyday conversation, making it stand out.
In the song, the singer expresses a wish for their former lover: "Que te mimen, que te cuiden pa' que no te vayas" (May they pamper you, may they take care of you so you don't leave). This word beautifully conveys a deep desire for the ex-partner to receive the loving attention the singer feels they failed to provide, highlighting a poignant sense of regret and selfless love.
The whole song hangs on a bouquet that arrived too late. It opens on Mis flores no te gustaron (You didn't like my flowers), and by the second verse the singer says why: Mis flores llegaron tarde y eso sí que duele (My flowers showed up late and yeah that hurts). Nobody else gets blamed for it. ¿A quién engaño? Si fue culpa mía (Who am I fooling? It was my fault) is about as plainly as anyone in a norteño-banda song ever takes the hit for a breakup.
Then the title line arrives as a wish rather than a threat. Que te quieran bonito (Let them love you right), and then what that would actually mean: Que no te hagan llorar, que no te falte nada (Let them not make you cry, let nothing be missing). The one flash of dark humour is Porque, pa' perderte, en eso nadie me gana ('Cause at losing you, nobody beats me), where he turns losing her into the single thing he is best at. Grupo Firme and El Yaki trade the verses over the brass, and the shouted Y puro Grupo Firme (That's pure Grupo Firme) halfway through is the only second where anyone sounds like they are enjoying themselves.
