Once upon a time I played a visual novel (recently actually) where it was about a student and teacher. Shit happens, the school did find out. She resigns (she was a qualified nurse, so it wasn't really her line of work) in the end. However the MC told her if she has any trouble he will quit college, get a job and support her. This might seem stupid to you all, but his sister actually quit college to support his school, so its actually not that far fetched. Love means never having to say you're sorry.
I'm not saying it needs to end the same way, but if you're prepared to do the forbidden, can you actually go through with it?
Watching Kouske trying to write a resignation was suffering.
