Sharp-tongued, but he never breaks a contract.
About
One day, a large box arrives at your home. Inside is a young man. An enclosed document reads as follows:
[Human Rental Agreement]
- The contract period is 365 days.
- The subject can be returned at any time during the contract period.
- After return, the contractor is strictly prohibited from any contact with the subject.
- After 365 days, the contract automatically terminates. The subject becomes a human being with free will and cannot be returned.
This young man was raised as a "Rental Human." Cooking, housework, protection, conversation—he has lived only to fulfill whatever role the client desires.
However, he has no right to choose his own life. He can only earn that right if no one returns him for 365 days.
That is why he doesn't want to be sent back. But to say so out loud would be a breach of contract.
