My Wife Hopped Out of an Egg

[More slice-of-life at first + a single heroine who grows up over time] The heroine starts out as a little girl.

Down-on-his-luck He Xi was unhappy with his life, so he went out to sea by boat to clear his head. After an accident capsized the boat, he washed up on an island and found a strange egg. He was rescued and taken home, where the egg suddenly cracked open and a little girl, around five or six years old, emerged, as lovely as a porcelain doll. Ever since she arrived, He Xi's life had gone unbelievably smoothly: he won the lottery, took over a haunted house, and even put his hateful stepmother's family in their place.

Little did he know that this entertaining life wouldn't last long before more trouble came his way.
