Summer Night Star

Summary

Transmigrated into the body of a ridiculously wealthy heiress, my billionaire mother sent me out to collect rent.

Miguel had just finished a brutal underground boxing match. He was covered in bruises. "Money is a little tight right now. Can you give me a two-month grace period?"

I shot down the request without blinking. "No way. If you don't have the rent by tonight, pack your bags."

The man turned around in silence and walked into his room to pack.

Right on cue, a mechanical voice chimed in my head. "System online. Host, your mission is to conquer him."
