Hachimitsu Darling
There's something really great about this manga. I really liked the gradual development of their relationship and that they didn't hop into bed with each other thoughtlessly. This was about a guy who adopts a stray kitten and when he has to go to the vet because it's sick he's offered a live-in housekeeping job.
Gyoumugai Renai
This is a collection of oneshots right? Looking at the chapter titles, it looks like it is but we'll see. 1) Main character was rejected and heartbroken after confessing to a coworker so he takes solace in confiding in his housekeeper, but when he overhears him fighting with a woman on the streets he gets curious about learning more about the housekeeper
Uchi No Tenshi Ga Kemono Deshita.
Video game artist hires a housekeeper because he looks like his character, but then the housekeeper declares that he's in love and enthusiastically pursues the otaku artist. Pretty cute, I liked this!
Daikirai Na Aitsu
Young, struggling actor gets a housekeeping job to make ends meet. He gets assigned a grumpy, difficult salaryman who quickly realizes how lucky he is to have his housekeeper and starts to fall in love with him. This was sweet. A really pleasant read!
House Backer
Super entertaining but WAAAAAAY too short! This is about a writer who hires a housekeeper, but gets a tough as nails guy instead of a woman. When the housekeeper gets a second house to look after the writer gets jealous and lonely and orders his housekeeper to fall in love with him. Then it just ends! Too unresolved! :(
Rakka
1) Ringo is a popular callboy who gets attacked and scarred by an obsessed client. The body guard who is in love with him saw it happen but did nothing and feels regret over it. Ringo just kinda accepts being with him because he can't be with anyone else :( 2) Former seme callboy remembers one time when he kinda raped a straight host worker. They run into each other years ago and the host has been looking for a guy who have sex with him the same way as the former callboy and the former callboy hasn't been able to cum with anyone else since. Kinda fucked up but ok, I guess. 3) CUTE. THE BEST. Older man's life is kinda a wreck after his wife died so he calls a housekeeper to come over and help but it turns out to be a cute, long-haired younger man who the older man is attracted to. He gets nervous about this attraction and tries to stop booking the housekeeper.
