I Just Became a Landlord, and You're Telling Me This Is Love Apartment!

1. Unemployed young man Zhou Fan binds himself to the "Stay-at-Home Sign-in System" and takes on the challenge of not going outside for a year. On the first day of sign-in, he gets a hundred million! After one month of sign-in, he gets master-level cooking skills! After a year, he gets the entire Cultural Garden complex! The System uninstalls, and the challenge is complete. He steps onto the balcony, gazing at the vast estate he earned through sign-ins, when he hears someone downstairs shouting, "Our apartment should be called Love Apartment!" "Kick off your shoes and dance, barefoot, walking in space... I smiled, and you still act so cool..." "The sun-warmed road is just the right temperature for youth, warm and comfortable..." Zhou Fan is baffled. Who turned on the speakers?
