more jealous - bin, i think he is irrationally jealous actually. neul also gets jealous tho . maybe possessive is better to describe neul.
more initiative in romance and sex? for romance i think bin simply bc he clearly loves acts of service and that’s more Visible, for sex i think both really but maybe neul is more bold / able to voice his desires easier
more of a sap? both of them, i was gonna say bin but just look at the way they look at each other… yeah. and the answers they give for repos are always soooo sappy and thoughtful
more experienced? neul
more freaky? honestly i think bin but he would have a hard time admitting some of his kinks, even though neul would be just as into it
