“VILLIAN!? Is that what you call me? Do you know what I have been through?

FATE dealt me this hand, and I'll find peace in it. Even if I have to end the world, I'll sit a king on its ruins.

I'm not a good guy. I won't even pretend that I am. But then again, who in this world can truly claim that title?

At least I know my heart. What about yours?”

.....

Chiron lived an unfortunate life, but his problems only got started when he was reincarnated in his dangerous Hit novel.

Behold, a lesson to all authors... MC's have it difficult too.

Shi Qing Xia is practically an angel.

Kind, sweet-hearted, and good at her studies, she was admitted to the top university in Taipei.

However, the living expenses for the metropolitan city were far greater than she had ever imagined, so she started to work as a private tutor for wealthy families to make ends meet.

On her first day of work, she met Zhao Yi Bo and Zhao Yi Xuan, a pair of neglected 16-year-old genius twins whose prosperous and wealthy parents heartlessly abandoned in Taiwan. Shi Qing Xia found them to be gentle, compassionate, friendly, clever, mysterious, pitiful and attractive.

But appearances can be very deceiving…

Because behind those sweet smiles…

Deeply twisted and cruel demons lurked, waiting to rip apart the wings of this angel, condemning her to an eternity of conflicted bittersweet suffering — a rollercoaster ride of a heart-wrenching, twisted, and tragic romance more extreme than what someone so innocent could possibly imagine.
