High school is supposed to be the time of a teenager's life, but for Rosario Alvarez it's a whole other story. Living in a place like Freeridge was hell already but when your dad is a well known gang member it's even worse because of the constant shit you have to put up with. The one thing Rosario knew for sure was that she was going to get the hell out of Freeridge as soon as she graduated. Oscar Diaz Fanfic. On My Block. I do not own any of the On My Block characters. I will briefly mention them here and there but for the most part this will be mainly about Oscar and Rosario's story and how they got together. This is the second book of the series of Oscar and Rosario's life, so if you haven't read the first one, go give it a read it's called "La Muerte." Enjoy! #3 Santo #63 Spooky
