Teaching The Tyrant Manners

Read manhwa Teaching the Tyrant Manners / Teaching Courtesy to a Tyrant /  The Tyrant’s Etiquette Tutor / 폭군에게 예의를 가르칩니
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.

Bending down to Rivi’s eye level, he asked in a soft voice with glimmering red eyes, “So you’re saying there’s no problem if you give me permission?” After hearing his words, Rivier’s heart pounded in trepidation. Tugging at her hand, he held it tightly, pulling his elbow as far as he could, before he stretched his arm out like a bow. Bam! Rivier accurately jabbed Croft’s abdomen. Wait, why is there such a hard lump?!
