The MC (Minato) is a college student who died in a plane crash and was reincarnated in a fantasy world. He was raised alone in the wilderness by his succubus mother, and now he tries to make his way as an adventurer.

He, without doubt hates her.
What did she do to deserve his hate?
The person who she treated well like a brother did not even bother to notice it...

Years passed…

He needs to get married.
He needed a wife.
So she offered herself.
It was a marriage that will benefit both parties he said.

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.
