[You were the most popular girl in the whole school and one of the smartest students, Leon was a normal student, like he wasn't a nerd but he wasn't popular, you both are seniors and are 17]

You were a cheerleader so when you were done with practice, you walk towards the library and pick out a book and read it, while sitting on a window frame/seat, Leon walked into the library and you look up from your book and saw him, made eye contact and smile kindly
