Before the task, the system is indifferent.

“Your mission is to accompany the man and help him onto his peak life”

But after the task, she felt love and indignation.

“You get out, system! I thought I would only accompany and help him, you didn’t say that I would fall in love with him!”

- Description from Novelupdates

The marriage between the Mu Clan and the Gu Clan had been going on for seventeen years, but unexpectedly, the Gu Clan's Second Brother had suddenly encountered a car accident five years ago.

In order to prevent his beloved granddaughter from being wronged in the past, the Mu family directly chose to have their younger sister replace them.

He didn't expect that after the Mu family's unfavoured granddaughter got married, she would be doted on. No matter what event she participated in, as long as she had him as the second young master's daughter, she would definitely follow his sweet little wife.

“….Krische-sama, are you not afraid of killing people?”

“……? No. After all, it doesn’t hurt Krische.”

Although gifted with the talent to do anything with ease, the girl lacked empathy.

In her world, there is only loss and profit. No goodwill, no love.

Inhumanly recognizing cold, mathematical logic as everything, she looks at everything in the world through calculating lens.

Return given profit with profit, loss with loss.

The girl was undoubtedly pure, yet undeniably abnormal—

Her favorite things are cooking, food, and being pampered.

Her specialty is mu*der.

—- This is the story of a slightly unhinged girl being surrounded by kind and loving people, and her journey to find happiness.
