When Hera woke up in the body of Heaven Liu, she embraced this life selfishly. It was a chance for her to live the life she had always wished for. Something she couldn't have in her previous life for the reason she was shackled in that life even before she was born into this world.
Hera was unable to take advantage of the escape route created by her mother, Felice, due to the circumstances.
How could she turn her back on that life when that hell had taken her parents from her?
How could she walk away when her mother died right in front of her?
That was why… Hera embraced this life even if the entire world would deem her selfish and unfair. Hera wasn't even interested in whether she would ever get an answer on how she got into this body. All that was important was she was alive. Dominic and Sebastian were a bonus that she was very satisfied with.
Everything was good.
Even if Andrea Ng tried to kill her, Hera was fine with it.
