From MangaProject:
Imagine what it is like to be raised by a gay father who insists that you call him "mom". The main character turns out to be a woman who doubts her sexual orientation, until she meets the right guy. She is so sure that he is "the one," that she goes out of her way to pursue him and then marries him lightning fast! Essentially, the rest of the story is about keeping the chemistry (a little twisted and crazy though).

On the eve of the wedding Nanako Marina finds her fiance with another woman. Accidentally met her priest whispers: "Take revenge on him, lost sheep." What will happen to Nanako now, after a meeting with two-faced messenger of God?

Volume one consists of two stories and one of them is called My Fair Gentleman:

He also decided to jump off the cliff because of a massive debt his brother has left him. However, since Yoriko has left over money she saved, she decides to give it to him, under one condition: he must be her ideal man
