cal is the opposite of ambitious, haha, but he's very social and friendly. she's older than he is, but that wouldn't stop him from shamelessly flirting if she was cool with it. he pretty much adopted nahay as a surrogate little sister, so he likely randomly shows up whenever she's working at the flower shop too. i could see the underground featuring local wines, so they could have an account with her dads' winery as well!
