I need to know the next chapter before I can hand verdict, the plot become fast too sudden.
The story is far great for me, development of story is not only through plot but also how MC's character would change through out the story or how MC influences others.
Read everything first before complaining.
There are people these days, for example, when watching anime for first 2 episodes comes they keep complaining how bad the anime is, but when the plot turned good they are becoming hypocrites.
Like how Overlord/Log Horizon start when they say that it just a copy of SAO.
why not everyone just enjoy reading manga than trash talking. if you can't like then drop it.
