Aaron, a wildlife biologist, became a military strategist right after a global war between nations began.He never wanted to participate in the war but he had to, because he wanted to continue his studies on endangered species the moment the war was over, but to his surprise, everyone in his unit were killed, including him, and the next thing he knew, Aaron woke up in the body of a young noble having a similar name to his.However, he also noticed he had awoken in a world different from Earth.In this world, demonic beasts ran rampart with only one thought in mind, causing them to feed on anyone they see, be it humans, elves or even magical beasts as well.During his first encounter with a magical beast, Aaron awakened a system which allowed him to bond with magical beasts and to obtain terrifying abilities from these bloodcurdling magical beasts, so he used his experience as a wildlife biologist to help make it easier for him to bond with these beasts.However, Aaron also noticed he could evolve these beasts if their loyalty towards him had reached a certain level, so he vowed in his heart to grow strong enough to protect those he cared about in this world with the hope of living a happy, peaceful life where he'll be able to focus fully on his passion as a wildlife biologist.

After witnessing her fiancé sleeping with another woman, Su Yu got herself drunk at a bar out of sadness and rage. At the end of the night, she accidentally slept with a ‘poor scoundrel’. This poor scoundrel was stubborn, always hounding after her to take responsibility after their night together. Pei Tianlin said, “You took my first time, so you should take responsibility.”Su Yu flew into a rage. “That was my first time too!” Pei Tianlin retorted, “Then I’ll take responsibility. Let’s get married.” Su Yu was flabbergasted. “Dream on!”

She had a feeling she was being tricked by the poor scoundrel, but he didn’t want money or assets. He just wanted a marriage certificate. Su Yu gritted her teeth in anger. “It’s just a marriage certificate! Sure, let’s go get it!” When her fiancé heard that she was marrying a poor scoundrel, he kept trying to persuade her.

“Yu Yu, I know that I hurt you, but you can’t ruin yourself by marrying a poor scoundrel out of spite. If you’re willing, I can marry you.”

Su Yu scoffed. “Go marry your mother!”

Who knew that on the second day of Su Yu’s marriage to Pei Tianlin, countless jewelry pieces, diamonds, high-quality custom-made clothes, luxury cars, and deeds to extravagant manors were delivered to Su Yu. The ‘poor scoundrel’ suddenly became a domineering CEO who spoiled Su Yu to no end.

Rumor had it that Pei Corporation’s mysterious CEO, Pei Tianlin, was a germaphobe. But when Su Yu was eating grapes, he obediently extended his hand to catch the grape seeds she spat out. Rumor had it that Pei Corporation’s mysterious CEO was aloof and difficult to get close to. However, he was nothing but gentle in front of Su Yu. Rumor had it that Pei Tianlin was a fair and unbiased man. But he would break the rules just to protect his wife, Su Yu. Justice and law were nothing compare to his wife!

Gu Nianzhi had no idea how to get the aloof and handsome Major General to fall in love with her.

His eyes were dark and serious. “…Seduce me. If you can do it, I’m yours.”

Gu Nianzhi: “!!!”
