Naruto System in One Piece - Chapter 82

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.

“Did you just marry the richest man in the country… by accident? How does that even happen?”Delphinia sighed dramatically. “I know, I’m such an overachiever. But it’s easy, really. Step one: drink too much. Step two: find the perfect man. Step three: say ‘I do’ before he realizes I’m a walking disaster.”“And the revenge?”She raised her glass. “Served cold, with a diamond bigger than my ex’s ego.”—After years trapped in a loveless, abusive marriage, Delphinia had one plan: leave her toxic past behind and never look back. But freedom isn’t as sweet as she’d hoped. With no family to turn to and no place to go, she crashes with her best friend…only to end up at a party where one too many drinks lead to one tiny (accidental) marriage to Evander Walton.Handsome, rich, and absolutely off-limits, Evander is everything Delphinia thought she’d never have. And he has just one condition if she wants to break things off: she’ll have to pay him back…for the huge diamond ring she barely remembers accepting. Broke and in no position to negotiate, she’s got no choice but to play along with her accidental husband and the lavish life that comes with him.Now she’s living in luxury, holding her head high, and plotting the sweetest revenge against the ex who tried to ruin her. Because if there’s one thing Delphinia knows, it’s that payback is best served in designer heels.

Please call me ex-wife!”The man was indifferent, pulling her into his arms, “I haven't signed the divorce agreement, and I haven't gone through the divorce procedures. How could there be an ex-wife to talk about?”
