I read the first several chapters a long time ago.
Do the brother and sister who are not related ever end up together? Or do either of them have feelings for the other?

well... hehe.. sorry for your waiting ) so
due manhwa, as I remember, Juhnhyk is tormented by thoughts of "wrong feelings" for his sister. It's not much of it, just a little. But it's clear for the reader because of his actions (an example, he removed on his own apartments) and there starting developments of 150 chapter: he almost confessing her and he kiss her. That's it. Sorry for my english ).

oh, it's not a big deal, you're welcome :3 enjoy your reading :) this manhwa worth it!)

Can i have the link please?
i like this... even tho he is weird, he is professional. and the story doesn't jump right into sex.
