Student x Teacher (will contain lemon)
But student will be over 18 yall dont worry

[m/n] is a very shy fox demon, so shy that he drops out of school and just locked himself up in his house, missing school and grew up.
His parents tried to do everything they can to get him to get out and get back to school but it was all for naught.

One day, they decided that they had to be stricter to [m/n], so they secretly enrolled him to Babyls and was put in the Abnormal Class with the teacher Naberius Kalego. As the teacher was informed about the shut in student, he had no choice but to force the kid to go to school. What happens then?
