MTL - From White Box To Supervision - Chapter 39 pre-presentation event

She, a renowned assassin of the 21st century, actually crossed over to become Su Manor’s most useless good-for-nothing Fourth Miss.

He, Jin Empire’s imperial highness, was an emotionless overbearing demonic tyrant with unrivaled talent.

Everyone knew that she was idiotic and good-for-nothing and bullied her as they pleased. But only he, the overbearing tyrant with the discerning eye, wouldn’t let go of her even if his life depended on it.

For the time being, let’s just see how the stubborn versus stubborn clash and play out in this good show of the chaser and the chased.

She is the slow-witted idiot of the Prime Minister’s Residence. Everyone bullies her. He is the most respected and unfeeling Prince, with frightening ability and absolute envy! Together, they are conferred an imperial edict of marriage.

She acts stupid and tries to decline in every way possible while he despotically escorts her into the wedding…… everyone ridicules the match, but no one knows that the “idiot” has transformed from a loser into a talent.

After the marriage, when they encounter the Empress Dowager examining the room, they act in concert with each other and pretend to be two mandarin ducks deeply in love. Afterwards, she laughs, “The performance has ended. Your highness, please return.”

He laughs softly, “Since you’ve got onto this Prince’s bed, don’t even think of getting off.”
