While InK is your classic shoujo that starts from high school to beyond, it has similar traits to Darling wa (...) Tsuki because they both express a married life that show lots of mishaps and conflicts between the couple.
Both female leads are quite desperate, needy and insecure for their handsome doctor husband too.
