YA realistic fiction novel from somewhere in between late 2010s and 2020/2021 about high school girl who was SAd and the guy who found her diary on the school bus

There’s a book that I found on wattpad and couple years that I’m like 90% sure was turned into a movie that I’ve been desperately trying to find. It’s about a high school girl that was drugged and raped at a party, and a guy at her school finds her diary she accidentally left on the bus. When he opens it to read it all the first page says in massive capital letters “I WAS RAPED”, he holds onto the diary and I’m pretty reading more of it for some reason, and she gets pissed at him when she finds out. They end up being really good friends and he helps put the guy who raped her in jail for five years because he got an audio recording on his phone of him admitting to it, something along the lines of “I just made her agreeable/more agreeable”? They end up dating and in a time skip to the future they’d ended up getting married and had a I think toddler aged kid who I’m pretty sure was a little girl. I can’t really remember any names or anything other than either or her little sister was named Raven
