Because I keep seeing people ask the same questions or seem confused I'll answer some things the webtoon doesn't really clarify well that the novel was more blunt about.
1.) Hyejin is female. The current avatar is her female alt. Her character on the other server is a male assassin, hence why she got kicked out of the other server guild for being a netkama. She's into fuckboys like Woojyeon, and not Seyoung. But she does think Seyoung is her precious friend.
2.) Heejae has never made any romantic advances on Yoona. They mostly met up for work (collabs etc) and usually there was always another person or two in the room like an editor or sponsor. He was just being vague in order to get info on Seyoung, but he and Yoona never dated or had a fling or anything. She's just being petty because she realized he chose Seyoung over her. That's literally it.

Tbh...originally I thought that...
Iheon had some kind of super powers he was hiding from Heemin, wasn't confident about confessing directly to him (or some other circumstances/conditions getting in the way of doing so, like a curse or whatever) and then sent him to the book world, so Heemin could fall in love with that world's Iheon, and then wake up and maybe look at real world Iheon in a different, more romantic light. Or something.
But if the spoilers I read below are true then I'm a bit disappointed that the abo/book world is the real original world because I feel like that specific that plotline has been over done, (even if the methodology - - - aka sketching part is interesting).

Siger really is my fav...
11/10 Good looking, straight forward/non-fussy personality, and stamina for days /blushh
I'm also a sucker for Knight & Princess trope. He fell in love with the current MC and is only loyal to her.
Eclat is a close second, but unfortunately he's loyal to the crown. Though I like that he's trying to suppress a burning flame. It's a classic.
Nadrika is in 3rd because while he's very cute and sweet...I'm not attracted to someone more feminine than me (not a bad thing, but sorry....not my preference).
After that, it's God, who I'm neutral on because we don't know too much about him.
Robert and Essen are last place for me; because I don't really know how I feel about Robert's sneakiness, and the fact that Essen used to love Arielle...talk about bad taste.
Am I crazy or are his moobs and shoulders getting bigger each chapter....
I swear it feels twice as wide in ch 50
