Don't expect any world building, this series never had one I'm saying this bcs I already finished the novel, the story really focus only on their relationships, and the conflicts are also only revolved around both of them. Even we barely know other people aside them, only the manager and dodong's family. There will be some development regarding dodong's job, but yeah I think that's it.

What happened to the world building? The other story was much much better.
