I hope you get well soon.As for the story I think this arc is getting dragged too much. I hope that MC can start his training and adventures as soon as possible because family drama are tolerable upto a certain limit. It has been forever since we have seen any action from MC or others. You know I would be better if there is a timeskip after this arc so that MC is sufficiently trained and can go on his own adventure. After that you can develop your story as you want.
