u know, if we be basing things in the catholic bible, we be each others' cousins, brothers, or sisters lol it's weird... i'm uncomfortable with incest in real life, but in webtoons, not so much since i know it's fiction. besides, just because there's incest doesn't mean people should tolerate it, we can still view it objectively and seek out the reason why they fell in love. At least in this manhwa, we are able to see why they developed feelings for each other.
