So, this is really a full on tragedy, read when you feel like crying.
I like the idea of the Hero becoming the Villain, however I'm still uncertain as to whether we will be following him and if he will "win". I don't know if I want to keep reading if it's not about him, also I don't like the whole "good" and "bad" heroes, the big amount of hero returnees there is, and how it seems like they are only taking over South Korea? (thought I have only read up to the 3rd chapter so I really shouldn't be saying much on that yet)
Idk I'll have to return later and keep reading and add my thoughts.
