I read up to chapter 40, and I must say the story is really bad and slow, the MC from chap 1 to 40 has nothing to him, except the fact that he doesn't want to abandon anyone *with the power of friendship* he will just piss you off the whole time, the only average thing is the heroine that's it, and obviously some fan service from her. I give this manga 1/10 and its not exaggerated really.
