How Should I, a Cartoon Side Character, Turn Down a Confession?

Bai Yingying believed the heavens had given her a second life so she could live in wealth, comfort, and happiness. She didn't even mind that everyone here had brightly colored hair. But her second life was actually in an animated world full of passionate battles and friendship. The friends Bai Yingying expected: red-haired, blue-haired, and brown-haired. The friends she actually got: a hot-blooded, justice-loving idiot; a cool, rational boy with a wounded heart; and a kindhearted boy with an exceptionally high IQ who was obsessed with mixing concrete. The visitors Bai Yingying expected in town: aloof, antisocial rich people. The visitors she actually got: villainous boys with tragic pasts and light in their eyes, who used indifference to hide their pain and were just waiting to be saved by a lecture. The legends Bai Yingying expected: bedtime stories for children. The legends she actually got: ...?! Why does every one of her friends have a legendary spirit stone?? Wait!! Why does she have one too?!! "Chosen ones, the fate of this world is in your hands!" Bai Yingying thought the world was doomed. Looking at this classic team of friends and the all-too-familiar plot, she finally understood. Wasn't this the animated series she'd watched in fourth grade? Later, Bai Yingying began to have her doubts. As her friends and various villains one after another confessed their feelings for her, she was baffled. Weren't animated series like this not allowed to have romance? Had she really transmigrated into a cartoon, rather than an otome manga??! Please note: Everyone has a one-sided crush on the heroine. It's a simple, sweet Mary Sue story. Theme: Don't give up when you run into difficulties.
