Ohh hello Rosa! Thanks to plotting with the others, I can definitely see the two of them being very friendly with each other since the past few year, Zita has been very much involved with the Vargas family and has interacted with them a lot in the past. I can see Zita taking a shining to Rosa somehow and being quiet nice to her whenever they meet. Maybe enough to drop by the restaurant or recommend it while Zita speaks with customers at her boutique? Whichever feels more natural or fitting for you.
