still don't understand what that convention means.
all I know is rom hacking for video games.
for the recommendation, as comedy is quite subjective
for me, I prefer the conversational type comedy with banter between the main characters rather than the typical physical slapstick comedy like panty shots, falling on someone's butt, wrong changing room, etc.
so for romcoms with actual romance as the main plot, with an equal level of comedy that I like
(I'll just randomly throw some since there are so many)
maybe things like
lovely complex,
dame na watashi,
Oh Roji webcomic,
Ichaicha okane,
kiyoku yamashiku,
bertia and
isekai nonbiri for isekai romcom, toorigakari already mentioned above,
sensei wa koi,
shiro seijo
those 10 for now, I guess
for the isekai, well that will be a long separate conversation
I remember there are already several threads discussing isekai recommendations, try looking there
