And if anybody's wondering how the main story ended.
Spoilers ahead....................................................................................................................................................................................................................................................................................................................................................................
Haeun failed his exam but then he heard about the gay novel contest held by the bookstore owner and puts all his energy into writing a novel. He wins and his novel becomes very successful. They then want to run away in the middle of the night with all the money he made but Haeun's dad immediately runs into them. However, he actually supports his son's plans of traveling the world/country and earn money as an author and so they leave the next morning with everyone seeing them off.
OF TO TAPAS TO READ THE LAST CHAPTERS!!
From what I can tell, chapter 12 will be the last regular chapter, followed by three specials (the author announced a Q&A and said that there will be three specials and the last one will be uploaded on 10/22).
I was really hoping for it to be longer tbh but it was still nice.
