I really think the author set up chapter one to mislead us. I really think its going to be the cilmax of the story; one that shows both of them finally stepping up for each other. Both of them have made a lot of character growth already, I think if anything maybe Seo In is goong to try and protect YW by trying to push him away but YW is going to eventually say fuck that and fight back. Thats my theory at least.
