Now, the peaceful station becomes the ultimate survival stage of cult madness and chaos.
Sometimes the protagonist is annoying morally good but that is what makes him unique especially since his goodness is not extreme but what you would expect of someone on a daily basis. In other words he is nothing special which is why he is special. A story that does not talk about heroic goodness but shows that true courage is remaining normal and extending decency to others even when you are trembling in fear yourself.
Poor boy but I ship you with the hippo. Hippo has the most heartbreaking and beautiful hetero love story tho.
I loved this series sooooo much. The protagonist is weak but has a strong willpower to live without regret. Although he dies again and a gain, he never misses the opportunity to help someone else escape.
