Kujibiki Tokushou: Musou Hāremu ken - Chapter 42

In her last life, as a cold-blooded assassin, she died without leaving her body behind and was reborn to the time when she was 15 years old with a supernatural ability.

Teaching a lesson to the parents whom are jerks, playing around with the selfish younger sister, slapping the faces of weirdo relatives.

Outstanding and high combat ability, who said that both looks and intelligence can’t be applied to the same person? With that said, she got the attention of a military officer.

“You’re suspected for the crime of murder, hacking into the general server system…… There’s too many crimes to be listed, you need to be apprehended immediately.”

Song Ye raised her eyebrow and got onto the military officer, “According to Young Master Qin, if I want to be cleared off of those crimes, is there any good suggestion for it?”

A certain someone’s eyes darkened and said, “Marry me.”

Everyone rumored that Z country’s young master Jun was cold-blooded, decisive, and not close to the female gender, but he took in an illiterate little girl as the pearl in the palm of his hand.

However, the little girl brought her case to the table. An illusion, it was all an illusion. What not close to the female gender? Which animal was crushing her every night?

“Baby, let me love you.” The man undressed her with his lips. She retreated pitifully, “Don’t want, don’t want, you’re bad.”

“Women love bad guys.” After eating he turned around to wipe his lips. She kneaded her pitiful little waist, tears falling, “This one is not a woman, she’s just a little mermaid.”
