I really enjoyed this manga. I really liked how the main characters jobs as a salesman and auditor played an important role in the story. Usually, being a salesmen in yaoi manga I've read is a backdrop for the story but in this manga its in the forefront as it actually has a role in developing a relationship between the main characters and those around them. Another plus about this manga is that the main characters gave me a sense of equality in their relationship that I really liked.
I'm glad she gained satisfaction from providing her technology to the servants of the mansion.
