Save Mr Lu

After failing his college exams, Lu Cheng was beaten to death by his adopted father. In exchange to redeem his miserable life, a thing called system struck a deal with him.

His mission: To be the shittiest, most scummiest, most douchebag and most brain-dead gong that causes the pure and chaste white little flower pain and misery!

Lu Cheng heehee-d. He was good at that.

However, he didn't expect that he had angered the beautiful little white flower to the point that they turned into a vicious venus fly trap and pushed him down.

Lu Cheng bit his blanket crying bitter tears. The system was a hoax. The system pretended to be dead.

The little white flower bit his earlobes and whispered lustfully, "This is your punishment for cheating on me!"
