On the Awakening of the Campus Romance Novel's Male Lead

Blurb: On the day before Christmas Eve in 2025, our protagonist, Du Yunran, receives a very special gift. A memory... of the future. Du Yunran: What? In the future, I marry two men and a woman? And I’m madly in love with that woman?! You've got to be kidding me! And so begins the story of a campus novel's male lead awakening, beating up the Mary Sue, kicking the harem novel to the curb, marrying his best bro, keeping his fujoshi little sister close, and becoming a winner in life. (Or something like that.) Warnings: ※ The style is sweet and fluffy, a light, simple read. Don't bring your brain along, or you'll be unable to resist the urge to complain. ※ The CP is Du Yunran (male lead) x Lin Yu (second male lead). More or less, they are both protagonists. ※ Their types are roughly a steady, scheming top and a gentle, scheming bottom (yes, they're both scheming). Whether there are side couples is up to you to decide. ※ This is a rewrite of the original, which I wasn't satisfied with. There have been quite a few changes. P.S. Although the story is set in 2025, it doesn't feel futuristic at all! And of course, the story won't go into detail about advanced technology from ten years in the future. The cover was made with a commercially usable Picrew character maker, plus the author's outrageously awful image-editing and layout skills. Theme:
