Crazy Love

Ruri is both hardworking and beautiful. Despite everyone's assumptions, she is inexperienced with love; she has not had a boyfriend in 15 years. What will happen when her world collides with Ryo, who is "perfect in appearance and content" but continues to be shaken?

Both ML had very poor childhood but as adult they are ultra rich.
FLs are kinda personal assistance of MLs.
Both MLs appears very tough from outside but once you got to know them you realize how much of a softie they are.

The pairs have a similar dynamic, and there are a lot of similarities among the male leads..... plus the potatoes!

On the verge of turning 30, Hoshino Rin, a “kind but unfortunate girl who takes care of others”, is at rock bottom, with neither a job nor a boyfriend.

Through her older brother’s introduction, she begins working as a housekeeper for Wakatsuki Iku, a genius programmer. However, the person she is assigned to is the very same “mysteriously insensitive man” who once ruined her marriage prospects. Although their relationship begins with the worst possible reunion, the housekeeping contract eventually comes to include a “romantic partner contract” as well…

A doting love story filled with strong possessiveness, led by an awkward “genius,” begins!
