Tonde Hi Ni Iru Natsu No Neko
centered around the patrons of a spirit cafe. 1st couple - a broke ass uke decided to sign up as the cleaning maid for a popular novelist while hoping to get some dirt on said novelist. But the only dirt he could find was that the novelist was a pervert and asked him to be his little pet toy. 2nd couple - basically slutty spirit uke looks for a new lover. he intended to search the human realm only to be stopped by the staff (?) at the border. they start to hook up cause uke was persistent on seducing him for some reason. 3rd couple - lonely boy and his guardian spirit (in cat form) gets united in the spirit world where he began working for the spirit cafe. overall made me smile. but thinking back, it could have been better.
