Xia Zhijun got the title ‘study god’ after scoring first place in the whole city. He’s the model of a good student in a teacher’s eyes: good grades, good manners, and quiet. When he wasn’t smiling, his entire body emits a cold abstinence aura. The girls only have the guts to look from afar and not get close.
Later, it was rumored throughout the entire school that even the study god would fight and hit on girls. Whoever dared to provoke his girl, he would teach you how to be a person at every minute. The night of the graduation ceremony someone saw him blocking Gu Siyi in the corner. He didn’t stop kissing even when she cried. He bit her lips and said in a raspy voice, “I’m going crazy…”
During college finals, Gu Siyi almost bursted out crying, “I’m such a failure. I won’t be able to find a good job in the future…And if I can’t find a good job, I can’t provide for myself…”
Xia Zhijun played with her pink earlobe and remarked, “I’ll take care of you.”
After they graduated, Xia Zhijun created a research company and Gu Siyi became the boss’s wife.
The commercial rocket, “Star of Siyi” was successfully launched. So everyone knew that the new technology superstar, Xia Zhijun has a wife who he spoils a lot.

The new book has been released “The Fierce Lord: Goodnight, Little Sweet Wife”. Everyone says that the mysterious family's Second Young Master Bo is cold, ruthless, and not close to women. Rumor has it that he is a high-ranking disabled man with hidden ailments.However, Mu Shini complains endlessly after hearing this. How is this hypocritical man not close to women? He is an outright rogue!She runs, he chases, and he confines her: “Woman, do you think that after becoming mine, you still have a chance to escape?”His endless entanglement makes her intolerable. “Divorce! I'll live with the child!”I recommend my other book “The President's On Top: New Wife, Stop Making Trouble”.

This stands at the forefront of strategy guides to Life (a shitty video game)!
