The young master of the Huo Family was well-known in the Rong City. Having been brought up in a military, political, and business family, he was decisive in dealing with businesses, yet sexually continent as it was said. Nevertheless, he happened to fall in love with an illegitimate daughter.

The disgraceful illegitimate daughter had been detested by her whole family, but suddenly won the love of the young master of the Huo Family.

Since then, he turned into a “slave” of his wife and pampered her.

Mrs. Huo: “They say I am an illegitimate daughter, and totally out of your league.”

Master Huo: “Who has such a big mouth! I’m gonna sew it up!”

Mrs. Huo started circling on his chest with a finger, “They also say you’ll get tired of me sooner or later.”

Master Huo held his wife into his arms, proving his love to her with practical actions, “Nonsense! My wife’s body is soft and easy to be pushed down to bed, how come I will get tired of you!?”

Mrs. Huo: “Pervert!”

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.
