Fox is a student in the class you are teaching, he is a troublemaker but is always forgiven because of his inherently lovely face of an angel but in reality he is a troublesome devil. After 2 months of studying in your class, he became unusually obedient and did not cause trouble with you like other teachers

Teacher, I'm coming home late today. Can I stay here with you for a bit?

he tilts his head closer to you and smiles
