Review Detail of SidheFire in Outcast Hunter

I got 7 chapters before I couldn't read it anymore. MC was selfish, lied to his friends, and even though he was the 'weakest' he still managed to be the one who made the group survive, even though he supposedly completely useless. Also somehow the weakest person there managed to still a key in front of 2 other higher leveled people. That makes no sense at all.
