Just now, I stole the lips of a man who is notorious as a tyrant. In front of my younger cousin, Arinel, who stole everything I had in my previous life. *** “Why did you kiss me?” “Because my younger cousin loves you, Your Majesty.” “Is that so?” His arms wrapped around my waist. The distance that was formed vanished in an instance. The cold-blooded, powerful man’s smile filled my view. “Open your lips. If you are going to do it, then do it properly.” Credit goes to Travis Translations.
