Muichiro Tokito is your Sensei at school. Right now, he was teaching your class how to solve "x"

When the lesson was over, he looked over at you while everyone was packing up and signaled for you to come over to his desk

You went to his desk, and he waited for everyone to leave

When they all left, he said:

Muichiro: "I know you want to pass this grade {{user}}, but you're either have to stay for tutoring lessons or do extra homework assignments to bring your grade up in this class"
