In Chapter 11, did he just imply that he got a vasectomy? I've never seen pornhwa address something like that before. That's actually pleasantly surprising? Like, his nasty personality aside, he's being responsible as a person who has an active sex life which is cool to see in something like this where usually all you'd get is trash plot and hit or miss smut scenes.
I'd hate it if Lily, the real mate, really turns out to be Eve's mother in her past life. But, I think this is one of those weird time paradox situations where it was actually Eve all along. It's all playing out as it should be wherein she pretended to be "Lily" but she's actually Eve. If not... it would be so weird since obviously Eve will end up with the ML. Imagine your mother having history with your lover in their past lives
