PS. Cover not mine, I just found it on google.

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

Cool and abstinent president X gentle and pure beauty

Wen Hua is getting married.

The other party is said to be the head of a Chinese family of European financial giants.

When we met, he was dressed in a suit and leather shoes, and his gestures were dignified and self-reliant, with a demeanor all over his body.

Wen Hua stared at him in silence, and after a while, she chuckled, “Interesting.”

After marriage, the two are model couples outside, but the queen respects each other as guests and does not disturb each other.

A friend asked her why she married Xi Mo.

She smiled at Yan Yan, “He is rich and powerful, if there is someone richer than him, I will marry too.”

Suddenly looking up, the man’s dark handsome face was hidden under the psychedelic lights of the bar.

Friends watching the excitement didn’t think it was a big deal: “Huahua, you’re miserable, go home and kneel on the washboard.”

It was impossible to go home, so she went back to her natal family.

Go back to your natal home if you get into trouble, go back to your natal home if you get angry, and go back to your natal home if you say something wrong

Mr. Xi is no stranger to this, and nine out of ten times he coaxes people back with nice words.

When he caught up with Wen’s house, someone was sitting in the living room eating oranges, saw him, and unhurriedly ate the last piece, with a provocative expression on his face, “Don’t move here, I’ll buy you some oranges. ”

“…”

Instead of being angry, he gently and patiently coaxed her home
