- Description from novelbuddy

He is a legendary business powerhouse, a King with a business empire. She is just an ordinary female student. A deal, – a paper marriage, a marriage for four years. Four years later, she turned away fearlessly. She thought that their path would never cross again, but he took her in his stride and refused to let go of everything about her, even interfering with her getting close to other men!

When Lu Wu opened his eyes, he found that the world had changed completely.The world before him did not have fancy magic, nor ultimate Dou Qi.What it had were summoners that form contracts with summoned beasts.And coincidentally, he was such a summoner, although not a professional one, and his first summoned beast was a piece of crap.But that was fine, because he also had a golden finger!

It had been two years since their marriage. However, every time he had s*x with her, he always did it from backwards.

She was more than angry. “Sheng Youting! Why do you avoid my face every time when you had me? Is it because that you are afraid to see it’s me rather than my sister that you get laid?!”

“Are you asking me to look at your face when I’m in you? OK, as long as you can bear!”

He was like a beast and all she could do was to accept what he gave…

Yu Lan had loved Sheng Youting for 11 years despite no response from him. Inferiority became part of her when she was with Sheng Youting. However, when she found it was so hard to continue her unrequited love and finally decided to exclude him from her world, her heart ached extremely and it nearly cost her life. It turned out that her love had become a habit and if it was stopped, she won’t be a whole man.
