I Guess I'm Back (student/teacher relationship)

Katie love, kat for short is smart and I'm not talking about strait A smart, more like I went to college when I was 12 smart. She is very capable but her mum seems to think she missed out on the high school part of growing up. so she's back at high school with her own age group, brother and incredibly easy classes. Luke jones is fresh out of college at 23 has taken to teaching. Knowing going back to his high school might Not be as fun as it seems he has to try his best. Teaching history, seems boring but he sets out to make it fun. But what will happen when they cross paths?
