Plot direction
Dual personality + self-attack and self-restraint setting.
There are many twists and turns, and I am still not satisfied after reading it. The love is also quite sweet.
If you are suspected of being a bastard, please don't enter if you mind.
Emotional direction
The crazy couple are a match made in heaven.
If you are a fan of The Phantom of the Opera, you can watch it as an original work, and please be careful to avoid lightning.
