I'm pretty sure it has more to do with the nature of the series. ^_^;

TG is a series about two species constantly fighting and killing each other out of need and control. At the center are two zealot factions who each think their species is superior so periodically clash which ultimately causes mass death and loss in the process.

The MC is a mentally unstable young man who became that way due to sever trauma at the hands of both species and is in a position where he can potentially continue to suffer because he works for an organization that can lead to the death of all his friends, and even himself.

TG just isn't a happy series. It has happy moments, but it's not a happy series. With the characters constantly threatened with death and their loved ones left to pick up the pieces, the ending being on an entirely happy note might not be a probable one.
