This year, Love, Simon is going to give us a whole new kind of cinematic love story. The film tells the tale of Simon Spier, a closeted high school student who confides in a mysterious online pen pal and, not shockingly, starts to fall in love. We've already been gifted with a sweet and sugary trailer that may or may not have made us well up with tears. Diehard fans will know this is an adaptation of the popular young-adult novel Simon vs. the Homo Sapiens Agenda. So, for those of you who want to know who's playing which character, we've got it all mapped out for ya. Invest in some tissues; Love, Simon hits theaters on March 16.
