I wasn't expecting incest when I started to read this

It's not incest, she was adopted....

Start again since you missed the point where she was ADOPTED

Yeah dude, I too want to adopt a little girl so that I can marry her to my son, smh you people.

Incestuous relationships has been practiced before to preserve money and blood

So i think they all have the right, since law are different centuries ago tho kinda weird today but common before so why the fuss?

Bro, that's on your son if he starts to like the girl you adopt.

This is a webtoon and these people keep on reading while forgetting this is not incest. That's what irritates me. Just stop reading if they can't understand the basic plot. ╮(￣▽￣)╭
