Chapter 75 was basically mingwa's way of saying Jiwon quit being a BJ now that he has DG Froschsaber
He was just considering. I mean the series is titled BJ Alex. I think it would be an appropriate ending to make the last chapter Jiwon actually making it official that he'll quit by deleting his account.
Just a heads up, the raws are up to chapter 81 at this point and mingwa says there's only two chapters left.
