Hari got adopted by Duke Erenst at 7 years old when she lost her mother. Even though she received all kinds of persecution by the three Erenst sons, she could finally escape that blood-and-tear inducing life when she was about to get married.
But what is this?
When I woke up from my sleep, I'm back to that hellish childhood! Is this a dream?!
Hmph. If I can't wake up from this dream,
I'll at least live without too much consideration for others now!
Just like that, Hari decided to go astray.
