Nigeru wa Haji da ga Yaku ni Tatsu (2016)

In each drama, their is a girl with very good qualifications who ends up moving in a socially awakward -yet accomplished- man.
This living arrangement will lead to a marriage of convenience.

If you want to see another social commentary regarding gender roles and marriage in Japanese society, Nigeru wa Haji da ga Yaku ni Tatsu handles it very well, is a lot lighter with no controversial elements, and really dives deep on the concepts of housework and valued work in society/relationships. Kareshi wo Loan is considered more controversial and definitely has some darker elements.

Remind me of Yokohama Ryusei drama....& still 1 of my favorite drama....If you like this genre this is a must watch romance comedy drama.

Both dramas centers on socially awkward characters and their desire for a domestic life.

Both comedies revolve around a couple who end in a Marriage Of Convenience. The male leads end up falling for the cute female lead by the end from their interactions with her. The ending is different enough, however, so be ready.

Two people decide to marry because it's more convenient (as well as financially more stable)
Yet main leads start to become closer over living together.
