After being inexplicably declared dead, Mu Cheng was bound by something that called itself a System.

016: Host, your task is to follow the script and play the villain, serving as the protagonist’s stepping stone.

Hearing this, Mu Cheng lowered his eyes and smiled sweetly. “Sure.”

A villain?

A stepping stone?

That actually sounds pretty interesting.

At first, watching its well-behaved and harmless Host, the System was brimming with confidence: It’s just a little task. Easy.

But who could have expected...

The pitiful one forced to live under someone else’s roof was cornered. “I’m about to get engaged to him, so you’d better figure out where you stand.”

The cruel, unstable childhood friend was trapped in a cage. “Since you came to me on your own, don’t blame me for making you my first target.”

The sinister, possessive big shot’s eyes were bloodshot. “You’re nothing but a lowly plaything, yet you think you can control me? Keep dreaming.”

If Mu Cheng wants it, Mu Cheng will have it.

Villain, mission: none of that matters.

In response, the System let out a shrill, despairing scream.

I told you to be the villain! Who said you could lock the protagonists in confinement?!

Mu Cheng: Well... I’ll be more careful next time.

016: ...

It worked hard for hundreds of years, only to end up owing a mountain of debt?

So... how did it manage to be so blind back then?
