She was the world’s number one genius assassin who struck fear with just a mention of her name. Ruthless and merciless, she killed without leaving a trace. Yet she was deceived and used by the organization, and met a tragic end.

When she was reborn, she became a fat and s*upid female student.

Fat?

She stunned everyone after losing weight!

s*upid?

The president of Peking University personally came to recruit her!

Useless?

All he has ever known to feel was loss and the only thing he can do is take.

He will devour their hearts and drink their blood if it is what it takes.
