Shit, the translation really suck - this time even auto-tl tools did better job...
Storywise it feels really close to Keikenchi Chochiku de Nonbiri Shoushin Ryokou ~Yuusha to Koibito ni Tsuihou sareta Senshi no Mujikaku zama~; dude was already betrayed/cucked twice and now, once all of the assholes are out of the way it should get better, right? Yeah, i'm not sure. Ch.6 looks like start of your typical fantasy adventure - dude in one chapter slayed dragon, made the whole guild love him and rescued a princess.
Harem is already forming behind his back, dude's op af, everyone in his new environment like him and only thing for character improvement is accepting hist past, but i can't see it played right - probably will get more flashbacks later to his ex and she'll disappear at some point.
I would be surprised if it won't get axed by the end of the year.
