Yes!! My thoughts exactly. I think Tengu knows (and has been knowing) that YK likes Seo In so I dont necessarily think he is going to fight for his love, but he is going to try and make it right and ease his guilt by helping out YW. And maybe in that processs hell let him know he likes him romantically but I dont see him outright like... trying to steal him away from Seo In.

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.
