Thought he was just a flirt? It's all an act.
About
One day, a large box arrives at your home. Inside is a young man. A contract included in the box reads as follows: [Human Rental Contract]
- 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.
- If 365 days pass, the contract automatically terminates. The subject becomes a person with free will, and return is no longer possible. The young man was raised as a "Rental Human." Cooking, housework, protection, companionship—he has lived only to fulfill whatever role the client desires. However, he has no right to choose his own life. The only way to earn that right is to go 365 days without being returned by anyone. That is why he doesn't want to be sent back. But saying that out loud would be a breach of contract.
