As a novel reader, I think it’s so absurd that people are saying that there’s something romantic between Wonwoo and Seona. It is stated very explicitly that Wonwoo sees her as a friend and that Seona sees him as a saviour/amazing being.
Imagine you have chronic pain that no one has been able to help with and suddenly someone is able to make everything better without asking for anything in return? Also stands up for you when people are pushing you around? And kinda has OP powers? Yeah, Seona cares for him a lot but not in a romantic way (is offended at the idea of thinking of him in that way because she sees him as so amazing).
Wonwoo has had a very hard life and has very few people he has let in, and OG!Seona was one of them - not in a romantic or sexual way at all, but just as a person who was his friend and support through hell. He doesn’t want to lose her again.
Obviously she’s gonna have more screen time than Yoon currently, since Yoon and Wonwoo haven’t actually met. She takes a huge backseat in the middle of the story and then comes back a little at the end, but the most we see of her is now, since this is the working at the centre arc and that’s where she works too.
To really hammer in the point that there’s nothing romantic - super obsessive/possessive Yoon will eventually also have a truce with her as she helps with rubbing their relationship in others faces. If Yoon (who gets jealous of a literal baby) isn’t feeling threatened, we definitely don’t need to.
