Quick Transmigration: The Host Is Sweet and Soft, and the Male Supporting Characters Follow Her Everywhere

Cheng Feinuan died, but not quite all the way. Then she encountered a System 120.

Cheng Feinuan: Are you here to save me?

System 120: (You're getting ahead of yourself.) Yes, Host. You need to save the pitiful male supporting characters. You'll receive a reward for completing each mission, and clear them all to come back to life!

Cheng Feinuan: Hurry, hurry! Male supporting characters, get over here! I want to live!

After meeting the male lead...

Cheng Feinuan: This guy looks familiar.

Zhao Yiyang: ...

First world: The young lady and her yandere butler.

Second world: The imperial concubine and her loyal guard.

Third world: The songstress and her silent listener.

No matter which world they're in, it's always Cheng Feinuan and Zhao Yiyang.
