I'd say HW told WJ about the past and his son and how HJ left him with hosu so now WJ kidnapped hosu to get revenge, but I don't think HW also knows these details. probably WJ got his memory back by himself. but the dracula man is 99% WJ.
okay so Jigu surely had queer vibes all over her, but after episode 6 where we got the flashback from 7 years…
actually eunji in her last live said that the kiss wasn't meant to be a "i love you" but a "how about this" and i kinda feel like since we only saw her talking about men and having boyfriends, they wanted to show us maybe she can swing the other way too? she may be bi tbh i know a lot of bi people who are more comfortable with their hetero side. i feel like she gonna have a female love interest, (i hope so lol)
the hospital fight scene pissed me off so bad,, their whole family is just trash. and WJ truely deserves HJ and that family. just want HW to move on from this toxic people and live her life.
