In order to combat this threat there has been a resurgence of ninjas that use Strategic Martial Arts, techniques that combine cutting-edge modern technology with a traditional foundation of martial arts and ninjutsu. The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

Beautiful doctor of Chinese medicine, Yu Gangan woke up from a coma one day to a cold, mysterious man. “Excuse me, you are…?”

Other people’s bad reputation, if not because of themselves, then it’s slandered by others. Jing Wan’s bad reputation wasn’t because of herself, but schemed by her future husband. Hong Yuan’s bad reputation wasn’t caused by others, but of his own design, only for the sake of marrying the woman he has had eyes on for two lifetimes! One unable to take a bride, one unable to marry. Because he was the number one handsomest man, but she wasn’t the number one beauty. So it was still her who has earned? What the hell?

After marrying, the husband’s close beautiful servant girls didn’t try to crawl onto the bed, but instead served her like an ancestor. The previous stewards didn’t monopolize the power, but instead handed over in great detail all the properties and even the husband’s private funds. So strange no matter how one looks at it! After getting along day and night, she discovered that her husband suffers from a severe case of crazy, please cure!

“Husband, just what do you like about me? I’ll change, just please stop being weird.”

His disease acting up in seconds, telling you with his actions, just how strong his possessive desires towards you are, that’s how much care you must give back.

Alright, for the sake of his disease not becoming more severe, and seeing how there’s no little three or little four and other little demons, Jing Wan rolled up her up sleeves and went all out.
