Created to design hotel rooms. And then became a small series. You notice that it is still really elaborated.
The cover shows the following characters from left to right:
Chairman of the Discipline Committee (left)
President of the Apprentice Association (centre)
Vice President of the Apprentice Association (right)

Yes, the 3 parts published so far are available in a gallery. But since I prefer such works as single chapters (because it quickly becomes far too many pages), I'll upload it individually. But I'm happy to link to yyyun's gallery, which contains all 3 previous works.
