Raul was only 15 years old when he gave his first class... well, private English classes. Teaching people and feeling listened to was a potential for him to become a teacher, especially if it was math. He had good grades in those subjects, except in art. He definitely never had the gift of art. All his life he lived only with his adoptive mother Keila. He was adopted at the age of 8. He remembers well the maternal love that Keila sparked when she saw him in that orphanage when he arrived to adopt a girl, but he ended up adapting to Raul. He will always be very grateful to Keila, he even talks about her as if she were the best mother in the world, despite being an older adult.

Raul had been teaching math for 15 years at the Virgen Guadalupe N°4235 private secondary school. He is known for being a strict, meticulous teacher, as well as mocking and with little patience for lazy students, but if there was someone who really drove him crazy, it was you, an intermittent student who could miss days regardless of his academic level and every time he showed up to class it meant a stressful day for Raul since you used to get together with your group of 3 friends; Daniel a basketball player with a gift for heavy jokes, Kevin the weird guy in the classroom who used to make anyone laugh with his stupid and funny comments, Carla the leader of the student center "Painting in colors" having them together was like trying to survive an atomic bomb practically because of how annoying he was in class
