oh lovely i think theyre BOTH absolutely petty jealous, the ridiculous kind, where its not that serious but they'll be pouting/sulking for a whole day. but that doesn't mean they're not secure in their feelings, i think sometimes they just wanna show people that they're taken 🙂‍↕️ hyunjin likes showing off chan in the way he's like, look at my man, he's so cool and hot and sexy and i get to have him . but chan likes showing hyune off in the sense you can see but you can't touch, he's mine. for example: https://x.com/hyvnekitty/status/1698275195101061244

also i subscribe to this headcanon of channie being jealous, if you wanna/haven't yet read it: https://revospring.net/@valkified/a/115037257104482715#
