I'm having a hard time following the stories and keeping track of characters in the lessons
Although it imay not be easy to identify all the characters in the Delavigne Corporation at the start of your training, the vast majority of users quickly become familiar with each of them and their unique personalities!
You can find more information about all the characters on the official Delavigne Corporation website: http://www.delavignecorp.com.
Note: The episodes sent after the end of the test period (first 10 lessons) are chronologically independent. Therefore, it is normal that you don't receive the same stories as your colleagues and friends, at least not at the same time!
