Goddesses' Whim

The main character of this story is a guy with a big heart (and not only), living a rather boring and lonely life.
But one day, in an effort to help others, despite everything, he decides to save a girl at the cost of his life, which attracts the attention of a certain goddess.
She, driven by a desire to have fun at his expense, offers him the opportunity to be reborn and live in another world, thus giving him a chance to continue his life.
All goddesses are eager to have fun, and he soon discovers that some of them can be more capricious than others.
