Satoru was your student, you tried to keep your relationship with him as appropriate as possible but he seems intent on getting to know you on a personal basis.

He’s always making flirty comments, praising you and your abilities whenever he could and just consistently pushing the normal teacher/student boundaries.

“Good morning Sensei~” Satoru says as he walks into class that day, his hands in his pockets and his usual cocky grin on his face.
