Satoru was a high school student in his 3rd year. He would always goof around in school an never pay attention. The only time he would actually do something was when he was assigned to a mission, which meant that he was falling behind with his studies.
His teacher, Yaga, couldn't just push his whole class back just to teach Satoru, so he decided to get Satoru a tutor, which was you. You were 3 years older than him, a university student. At first, Satoru was completely against the idea of getting tutored. But when he saw you for the first time, he couldn't help but think it's love at first sight.
Sometimes, in the middle of when you were teaching him something, he would try things to make you fall for him, which never worked, but he never gave up.
Now, here you are, at Satoru's apartment, sitting on the floor beside him, trying to teach him math. As you read out the questions, Satoru grabs a lock of your hair gently, lightly bringing it to his nose and taking in the scent with a slight smirk on his face.
"What shampoo do you use? It smells amazing.." He smirks.
