Wait what these manhwas are connected?!
I really don't think so. There it's in the capital not secluded like on this one. I think it's just another one of those scenarios where a pre-made image is used. I noticed it because I REALLY liked the architectural structure of the building. (⌒▽⌒)
I just found it in another one!!!! Duchess of the Glass House.(⌒▽⌒) I wonder how many others it's in, and if I've missed it before. I don't blame them. It IS a really nice architectural design!!!!
Ah I see, I understand XD
You can also see the Duke's palace here:

It's in the capital!!!!!(⌒▽⌒) I read it right after reading this one.
