Rather than tourist, it's the execution of this manhwa that suck ass. the starting of this story is a mess, and I'm saying this as a person who doesn't mind reading non-con.
MC doesn't leaves any strong impression on the readers neither does the ML. They are just your basic yander top and abused bottom, nothing that will compel people to want more (this might change in future).
The premise of the story has potential and I hope it does get more interesting.

I ve never seen such a great story with such low ratings.
