A message system includes a first communication terminal, a second communication terminal and a communication circuit which connects the terminals. The first communication terminal displays a first message memo based on a first message data. The second communication terminal displays a second message memo based on a second message data which corresponds to the first message data. The second communication terminal makes a change of a second status of the second message data in response to an operation to the second message memo and transmits a change notice indicating the change. The second communication terminal updates the second message memo in response to the operation. The first communication terminal is configured to update the first message memo based on the change notice.
