Help finding a book

Hi! So I’m trying to find a book that I read in highschool, that was 6 years ago so hopefully that’ll give a good idea how old the book is hopefully. But this book from what I can remember, is this girl was kidnapped from her home, and they faked her death, so basically her old life was gone. She was trained to be like a secret agent or something, but they injected her with a serum where she has the urge to protect this guy in college, and he has a photographic memory. At the end of the book the organization she works for wants to kill this person because of something (I think he like made something or saw something I don’t remember) and she vowed to protect him, and basically her and her boyfriend went rouge. If you could help me figure out what the book is called that would be wonderful!!! Thanks in advance!! It was a Young adults book I believe, I remember reading it in a book club in highschool
