I think the chef is an old term no longer that used, called metrosexual. 🤓👆
I thought metrosexual was more about a guy that actually participates in self care and hygienic practices that were labeled "feminine" before, like getting manicures, pedicures, dressing well or putting effort into their style?
In this case the chef is just a straight "feminine" type guy. Which Japan likes to label as the guys that love teddy bears, cute things, pastel colors and flowers-- as well as take up "feminine hobbies" like crocheting, sewing, other whatever random "feminine" things lol
