Seikimatsu Darling and Close the Last Door are a perfect match. Fluffy yaoi comedy and some rather rocky relationships form the theme for both titles. The setting in a working environment is also the same and there are plenty of jokes that will appeal to the yaoi fan as they mock the genre in a very light hearted way.
