Waking up as Harriet

Harriet wakes up from a 3 month coma and doesn't remember anything... nothing at all.
After going back to school desperately trying to get back her memory, Harriet eventually finds somewhere where she can belong. She begins a new life with a new crown and an awesome boyfriend, who just happens to be the captain of the football team. She likes who she has become, but is this the real Harriet, as it certainly not the old Harriet.
Chris desperately wants her to remember who was is so their friendship can remain, but he finds himself quickly pushed from her life.
Has Harriet changed too much? Is she still Harriet?
