The landlord has multiple personalities and wants everyone to pay him.

[Four personalities + pure love + extreme love triangle + sweet slice-of-life moments]
Ye Shu graduated and was so poor he was almost sleeping under a bridge, but then a windfall came his way: he moved into a top-tier luxury mansion for a monthly rent of only 800 yuan!
Landlady An Suxue, clutching a carrot pillow, timidly handed over the contract:
"My only requirement... is that you can accept me occasionally 'changing the person'?"
Ye Shumei happily signed the contract, only to realize that "replacement" was a literal translation!
His landlady is a whole "girl group" living inside her!
Human-Machine Companion: "Based on the current situation, you and I being together is the optimal solution."
Boss Xia Qing: "You brat, you dare say you don't like me?!"
The wise and intelligent older sister, Zhi Qiu, said: "Little Shu, tell your older sister, don't you like me the most?"
Socially awkward bunny An Suxue: "Brother Ye Shu...you...you like me...right?"
Until one day, the four personalities reached a consensus and pinned Ye Shu to the bed.
All Personalities: "Tell me! Who! You! Really! Like! Us! Most!?"
