I'm Happy is the story of Nicole Jones, a grade ten girl with a small social circle. When things with a so-called 'friend' fell apart and hurt Nicole, she resorted to hanging out with three people, Austin(her brother who is a year older than her), Callie(her cousin who's also in grade ten), and Justin (her cousin who's in grade eleven with Austin). They are super supportive and when Nicole became very introverted that was exactly what she needed.
Now, Nicole has to find how to navigate her life. She needs to learn how to be a grade ten student, how to navigate high school, and she has to learn how to be herself, as well as who that is. In Nicole's journey to finding out who she is, she is faced with challenges. How can she find who she is when there are constant reminders of last year?
With her brother and two cousins by her side, Nicole does her best to find herself through the events of the school year. But between school, parties, and bullies she finds the difficult task even harder to complete.
