NINGEN YAMETAI YONEZAWA-SAN

Haru Yonezawa is an outstanding office manager who is looked up to by all of his teammates. On the surface, he is cool and collected, never getting his feathers ruffled by his grouchy boss. But the truth is he has a secret hobby that, if anyone found out about, would destroy his elite image. Every night, after a long, stressful day at work, he unwinds by dressing up and roleplaying… as a dog. Looking for a new “master” to help meet his needs, he calls upon a call-girl, who shows up and is none other than one of his subordinates from work!
