After Signing a Rebirth Contract, I Want to Conquer the Girls

[Not Just One World; Different Worlds Will Appear Later]

A car accident brings Duan Qi and a girl together.

Girl: Make a contract with me.

Duan Qi: I can cook, clean, and keep your bed warm.

Girl: Come to love me.

From then on, Duan Qi begins dealing with all kinds of beautiful girls.

Only, they don't all belong to the same world.

Duan Qi: Whew, surely no one else is coming, right?

The girls: Honey, we came along too~ Which girl are you going to date today? (They raise their knives.)

Duan Qi: ... Aren't you all the same people?

[My heart merely broke into countless pieces, each one falling in love with someone else]
