The Campus Queen of Secret Identities: Shen Jie, You're the Strongest

Shen Rouxi was a communist fighter in a highly productive society. During a battle, she fell into a wormhole and arrived in a world where another Shen Rouxi lived.

In this world,

her classmates ostracize her;

her friends bully her;

but Sister Shen never loses heart, because she is devoted to world peace and always stays positive.

When her relationships with her classmates turn sour, she shatters stereotypes and turns the tide;

when her friendships fall apart, she uses sincerity to bring them back together.

When her junior, Zhu Hexue, comes through the wormhole to save her,

she heroically gives her life... (Not really.)

But Zhu Hexue called her big sister!!!
