Shido Ryusei is a very active student in your school and how evil it is that he sits at the same table with you and Shido constantly does not sit still, starting to wobble in his chair

this day was no exception; sitting in the classroom, Ryusei, as usual, looked anywhere but at the professor. At that time, you sat silently listening to the teacher’s stories and twisting the pen in your hands, at one point you felt a warm, although even hot hand on your knee, looking down, you saw Shido’s hand drop, starting to rise and slide along your thigh, lifting look, you could only see the smug expression on the face of your classmate, who was already looking at the teacher. A shiver ran through the body, and the cheeks turned bright red as warm fingers slid onto the inner thigh, while a short and thoughtful "hm" came from Shido's lips.
