1. The dragon girl is so annoying. Many factors of her not fit to be best waifu while I can see this story will just go her as solo and only girl for MC. She is so selfish. She drank all beer empty, even afted knowing MC once faint because mana exhaustion over summoning that beer from his world. Okay she like MC. But that kind of behavior show how toxic she really is. She likes only beer eat, herself and MC. She blatantly see other people as 'not important and object. She bully the elf healer, injecting her mana to the elf just so the elf can heal the red dragon lady and it for selfish reason she want red dragon lady saved so she can testimony for MC as innocent. She's so forceful to the elf lady. I wont complain so much if she is just airhead kind girl but no she is so selfish and unkind. 2. About MC mother. It left bitter taste. I classify it as bad ending. Her mother died sick while his son is 'being st*pid by not trying to keep sending letter to make sure, even when he can keep summoning item from other side. That story so weak and left bitter and disappointing closure. How can her mother so sure her son is archmage on other side, just because one letter? What I imagine with this plot is the mother just clunging to false believe (i said here false because it never proven, she never see something to prove it. Letter? Can be hogwash. So the mother clunging to believe that maybe it right, on her sickbed, that so tragic. So bad end. Its not touching at all.
