Do Korean people not wear wedding rings?

I don't think so, maybe they forgot. In another manhwa that I read the main couple wore the wedding rings after their marriage.

Oh ok. Maybe it's a personal choice? I suppose you don't have to wear wedding rings if you don't want to?

It depends a lot on who wants to wear a ring. As far as I know there are two types of marriage, the most traditional and the most Westernized, use alliance is something more western, in some sleeves and manhwas some couples use, in others not. It's kind of a cultural thing and a choose too.

ok thanks :)

You are welcome (=・ω・=). When I wrote there sleeves, it was the cellphone broker, it was to have been written "manga ". Sorry. （￣へ￣） ┗( T﹏T )┛

Haha I hate it when that happens.
