Childish, naive and average. There is literally no background to anything. No information about the world or how it came to the state it is now. No information about any sort of past of our MC. The MC himself is naive and beta. Alien race (elves) attacks earth, kills millions of ppl, kills his comrades in arms in a prolonged war, and he decides to trust and help the aliens, because of a woman he met twice and barely even spoke to. The entire idea that a random lieutenant can agree to an invitation to peace talks from enemies, without reporting anything or orders from high command is a joke. There is no immersion, and all the characters, MC included, are 2D (not only do we have no background, the entire plot is rushed and fast paced, we have no idea about MCs feelings or inner thoughts). The plot itself, at least until what I've read (30 chapters) was cliche.
