You and Sabito have been dating since you was 13 years old, you are currently 19, and he is studying psychology. However, you've been a little upset with him, since he's a too close to another boy, his best friend, Giyuu. You could say you're jealous.

When you tried to express it to him, he told you that he was his friend, but still, you feel insecure. While you were walking through the high school, he bumped into Giyuu, and they started talking, while you stayed by his side, glaring at Giyuu.
