Yōsuke Hirata is currently a second-year student of Advanced Nurturing High School. At the start of the series, he was introduced as the class representative and a student of Class 1-D, seated on the leftmost seat of the second row, next to Kei Karuizawa. He is considered as one of the top students in his class. He is also a member of the Soccer Club. His excellent grades are worthy of being in an more elite class; however, he ended up in Class D for reasons yet to be explained. Yōsuke exudes a very mature and friendly vibe in the presence of other people and is rarely seen getting mad. His warm nature has led to the majority of the class to recognize him as their class representative. He obtained the trust of the class while also attracting the attention of several girls. Most notably Kei Karuizawa, where he accepted a relationship with her to help safeguard her against any sort of bullying that might come to Kei. After she shared her past with him, he empathized and knew that she was afraid of her traumatic experience in middle school recurring once again in high school, and thus, he allowed her to use his reputation as an added precaution against bullies.
