Wait a minute. It looked like in the last chapter sensei was going to tell his father about them so why in the extra the student said they didn't tell their parents nor friends. Even the glasses guy knows about them
At first when the picture popped up I thought it was going to be something sad for him but his face and the way he talks (such adoration) tells me that he's happy.
something like ... "he's really kind and thoughtful and even helped me this time. to repay him, i should be his lover because he likes me."like this? @Anonymous
or " my tastes are fucking terrible so maybe this time i shuold go out with someone totally diferent and see what happen"
I'm buying this, there you go, scanlation works.
