Re:Zero Kara Hajimeru Isekai Seikatsu - Chapter 75Arc 7, - “I know”

Yu Yuehan is the usual rich, perfect, aloof president—the richest man in City H; but one day, a female toddler suddenly appears in his life as his daughter! Despite being certain that he has never touched a woman before, DNA tests certify that the toddler is his! He soon becomes a good ‘daddi’ for the little toddler, Xiao Liuliu.

Two years later, for some inexplicable reason, Xiao Liuliu becomes very fond of a trial nurse, Nian Xiaomu, hired to take care of her. Nian Xiaomu has a strong personality and refuses to let anyone bully her. Constantly wary that anyone might cause harm to his daughter, Yu Yuehan keeps a constant watch over Nian Xiaomu. However, his black-bellied daughter has plans for her father up her sleeves… Over time, Nian Xiaomu reveals her charming side bit by bit; and for the first time in his life, Yu Yuehan is drawn in by this mysterious woman…

“Daddi, you are so handsome!” Xiao Liuliu blushes.

“Daddi, I want hugs!” Xiao Liuliu coos.

“Daddi, I want a younger sister! Quick make one with Mommi.”

“Daddi…”

Yu Yuehan says in a deadpan fashion, “I have never slept with any woman! How can I have a daughter!?”

“Did Mommi sleep with you without you realizing it?”

Yu Yuehan: “…”

A certain Xiao wang* embraced her who was in men’s clothing, rolled over onto the ground, not neglecting to kiss her with burning kisses.

She who was going to war on behalf of her brother yelled out, “Wangye*, I am a man! A man! Do you see clearly?”

Wangye acted as if nothing happened, accurately captured two fragrant, soft and sweet lips, one kiss after another: “This wang am recently sexually inclined towards males!” A certain female’s tiny waist was being crushed as she tearfully pled, “Wangye, please spread the rain and dew!”

A certain Xiao wang: “There are many potential lovers to choose from, but this wang only wants one.”

She, Linghu Shui Yue, a military doctor from the modern era, has reincarnated into a stupid sixteen year old girl?

She stupid? Then she’ll stupidly hit Qi* wang! Fortune favors fools! How about changing a husband to play with? What is Qi wang? She heard that You* wang was the world’s most beautiful man! Sleep, of course one must sleep the world’s number one beautiful man! Marry, of course she must marry the man all the women in the world want to marry!

But, isn’t this man too black-bellied? There was no need for her to even think about it for the man voluntarily presented himself at her door and used all sorts of wiles and methods to marry her as consort! There’s a conspiracy! Then come! And see how she sees through the subterfuge and completely demolishes it.
