How to send a notice to become a happy rider when happiness runs bad?

The reason why Le Run broke the contract and became a Le Run rider was that there were not enough hands. According to the relevant information, it shows that the number of registered people on Happy Run site is not enough to meet the number of people in this period. Those who escape halfway will be permanently hacked, for whatever reason. One week of running is a cycle. After running for one week, you can continue to renew or cancel the contract. If you cancel the contract, you will not send a text message to remind you to quit Le Run next week.
