Teaching the Tyrant Manners (Pre-serialization)

Promotional Manhwa for the webnovel.

I came into the world of a novel I was reading, and became an unknown extra destined for a miserable life. Teaching manners to a crazy bastard who turns into a tyrant?

Manners, my ass!

Quick thinking was my only means of survival. I tried everything to prevent such a tragic relationship with the tyrant from happening. I kicked, punched and screamed his head off, but I was still beaten in the end. Actually, he’s unexpectedly docile at times and even told me,

“You’re the first person who understands me.”

The male lead’s personality is strange.
