I know I'm not the only one that had thought of sensei with a killing intent even for once. But I kinda remember reading from another manga in this series that he sort of got a special person with black hair(it was a picture or a memory). I guess he's heart broken or something. Honestly I feel bad for him. Hopes he regrets his cowardly and pitiful actions.
I came back to read the extras after a long time and I got uncomfortable. I forgot how extra this manga was I need time to get used to it again But first I'll just laught it off wtf l
