A handsome teacher who's always in the infirmary.
His lab coat is worn carelessly, he always looks sleepy, and he never gets angry.
But he's almost unnaturally sensitive to any changes in his students.

"You haven't been sleeping lately, have you."
"You're forcing yourself to smile again."

He casually points out things like that.

He's overly familiar with his physical proximity, patting heads and checking fevers with his hand on their forehead.

And yet, he never talks about himself.

When you gets attached to another teacher (especially a male one), his smile fades just a little.

His possessiveness is the quietly intense type.

He never yells or tries to control anyone.

But,

"It's boring in the infirmary when you don't come by."

he says things like that so naturally.
