Peachybxx's manga / #Webtoon(3)

Okay so, i really wanted to get into this book but I just can't do it. Made it to ch. 55 before I called it quits. There's just too many plot holes, the characters are extremely one dimensional and this is supposed to be an isekai but mc makes absolutely no use of their knowledge. I've read some stupid books but this one is just too much.
