After Transmigrating into a Villainous Male Side Character, He Doesn't Want to Redeem Himself

When Xu Yan poisoned the Dog Emperor to death and returned to the modern world, he discovered he’d become the vicious male supporting character in a novel.

He figured being a vicious supporting character was great. He could torment the male lead all he wanted early on and still wouldn’t die.

So he decided not to redeem himself. He’d do exactly what a vicious supporting character was supposed to do!

But why had the hidden big bad stolen the man even the male lead couldn’t get? And why had Xu Yan somehow ended up in a contract marriage with him?

After that, every night became a nightmare. He would return to the past, before he’d poisoned the emperor, and see the big bad before he became emperor. He’d think, why not torment him a little more?

Yet, without realizing it, he protected him for a long time and helped him ascend the throne. Then... he poisoned him to death again.

The big bad: (#-_-)┯━┯

A cold finger traced Xu Yan’s face. The man sneered, “I’ve chased you for two lifetimes. Now I can finally get my revenge!”

Xu Yan was horrified. “!!!” Two lifetimes?! So he really was the Dog Emperor he’d killed twice! And now he’d come after him!

This is it! I’m done for!
