The Full-Time Wife Escapist
A manga about a woman who enters into a common-law marriage with a man to make a job out of being a house wife.
We covered this series recently but afterwords I ended up diving into it and read the whole thing. Although it is ultimately a straight-up romance manga with numerous cliche, I really loved how they approached these overused storylines. Breaking down the relationships of love and physical contact logistically was hilarious and refreshing. I also appreciated that this was a story about adults dealing with love instead of younger teenagers.
I loved it so much that I even watched the live-action drama, which was also excellent!
