Sea of Sand: It's Fine to Be Everyone's Favorite

[Everyone’s favorite] + [Mary Sue] + [Multiple male leads] + [OOC] + [Power fantasy with a strong female lead] + [Chaotic timeline] + [Invincible] Read at your own discretion, though I hope you’ll give it a try. You can also treat it as a crossover of anime and films. Please stick around for a little fan of The Grave Robbers' Chronicles. I may ship couples, but I might also have a bit of a self-insert romance. If you ship male/male couples, you can leave. There’s no central plot, but lots of exciting content will come later. Feel free to skip the first chapter. The heroine will transmigrate to the past and people will also travel back the other way. She’s very chuunibyou and comes across like a heartbreaker, but that won’t affect anything. Any male character could fall in love at first sight, including Jiang Zisuan, Liu Sang, Wang Can (and the rest of the Wang family), Ping Xie and Hei Hua, Wang Meng, Zhang Rishan, and the Zhang family boys. The main story may be shorter than the bonus chapters, which will include lots of individual romances between the heroine and the other male leads. You can also go straight to the bonus chapters. Most importantly, there are crossovers with other anime, including Jujutsu Kaisen and The Outcast, and the heroine has special abilities. She doesn’t know the plot. I read these a long time ago, so I’ve forgotten most of the details. Sorry for the OOC. There may also be bonus-story sections mixed in as you read. If you come across one, run! Run fast! Don’t worry about it, just skip to the next chapter. I’ve learned my lesson. Please go easy on me.
