- Description from novelbuddy

When Evelyn’s loser fiance steals her company's secrets and elopes with her prostitute mother, she finds herself facing impending bankruptcy. But unexpected help comes in the form of an unusual offer from her business rival and ex-boyfriend, Alexander Langford.“Bear my children, Eve, and I’ll save this precious company of yours.”To everyone else, Alexander is the heir to a billion dollar fortune, and the acting industry’s handsome darling. But to Evelyn, he is nothing more than a cold-hearted, arrogant man she dumped for being a compulsive liar years ago - but unknown to her, he has never lied about his love.How could Alexander miss the golden chance to hit two birds with one stone? He gets his inheritance, and a family with the love of his life. Now, if only dear Evelyn would stop thinking the worst of him…[Strong female lead x doting male lead.][EXCERPT]“You’re out of your mind,” Eve snaps. “You could have any woman in this world, and you want ME to be the mother of your children?!”“Why not? You’re smart, savvy, and fucking hot,” Alex says as he takes a step forward, trapping her body between his muscular arms. His dark blue eyes gaze deep into hers with unbridled lust. “I want our children to have the best from both of us. Our children could take over the world.”“There is no ‘our’,” Eve says coldly, pushing him away. “I will be the surrogate for your children. This is nothing but a business deal. There is NO love in this contract. But in exchange, you need to do something else.”“And what is it?”“Help me take down my ex-fiance. That bastard deserves to die after fucking my mom and ruining my life.”Alex chuckles. “It’s a deal then, sweetheart.”It was nothing but a business deal at first. But what if the line between business, love, and hatred were getting blurry as they got entangled too far and too long?[Power couple, slow burn, getting back together.]

Unconditional obedience to him? Dream on! Regrettably, after marrying Tang Yuchen, An Ruo's daily thoughts were of escape, escape, and more escape! Someone grew furious, “You want to flee? The only way out is if you die, or I perish!” Fine, she chose death! Yet he laughed wickedly, “Woman, do you intend to kill the son in your womb?”

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

He died in an accident and was reincarnated into another world. The Gundam works he had read before his death and the techniques in various military novels could be brought to another world.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?
