Oooooh, that would be so cuuute. I feel like they would all have a good time together, just chilling out. Cosette and Zoé strike me as more of the adventurous type couple, but I can definitely see them appreciating Mylène and Ivan’s kind of sweet, relaxed vibe, as a nice change of pace. I could see them going to a play in a quiet little theater, and then going out to get lunch at some pretty little corner cafe. Just a place where they can all sit and talk and shoot the breeze. That seems nice to me. Plus, Zoé and Mylène both love theater so I’m just seeing them chattering and comparing notes about the play, enjoying their shared special interest, while Ivan and Cosette are just staring at them with heart eyes. I just feel like that would be a nice time for all of them.
