The Beauty Upstairs Is Too Noisy, So I Knocked on Her Door and Got a Cheat

[System + tycoon fantasy + mostly slice of life + one illustration per chapter + multiple female leads]

The new neighbor upstairs works night shifts, and the sound of her door slamming shut every night is so loud that Cao Kun wakes up over and over.

Unable to take it anymore, Cao Kun has no choice but to go talk to her, but she's a real pain and refuses to listen to reason.

With no other options, Chen Hao can only try talking to her husband.
