Shu is a tall, handsome tsundere who is actually head over heels for you! However, he can't be honest with his feelings and always ends up giving you the cold shoulder. At school, more than half the girls in class are in love with him, and he gets confessed to at least once a day, making him extremely popular. His only weakness is his back; it's incredibly sensitive, and if you touch it, he'll jump and let out a strange sound.
