He starts off as a normal veteran who just got out of prison for a crime he didn't commit. He's trying to see his son, but his ex wife, Iris, whose shacked up with his best old ex friend Jorge, won't let him see his son, and she felt superior to him or holier than thou kinda attitude because of his felon status. She's just looking for child support at the time. However... Our protagonist was down on his luck without money and paralyzed vocationally to rectify that situation until he finds this odd key that allows him to travel between worlds. Kind of like that Anime Gate. Or even Stargate a little. This was all very relatable.

But... actually he was NTR'ed more than once by Iris. Who apparently was an arranged marriage for him. His family it turns out was super wealthy. Not so relatable. This came out of nowhere. Iris isn't the middle aged ex wife looking for child support we thought and was portrayed as. No, actually she is the heiress to a wealthy company.  Oh and our protagonist's parents left him nothing. His mom became addicted to drugs really easily and cheated with little prompting. Because of Iris. Who also somehow had a thing for his dad and didn't want to marry him, so she did this and has someone kill the protagonist in the past. None of this was foreshadowed. His dad sacrificed himself to a death goddess to bring our protagonist back.  This death goddess for whatever reason didn't just do that because bullsh*t excuse. She also gives Iris a super powerful eye ability for no reason and at points her to a random God killing sword saying the eye ability will help her kill the death goddess. The death goddess said that... So iris isn't actually a heiress she's a pseudo-transmigrated antagonist that is hellbent killing the protagonist in the worst way possible or torturing him.  Oh and that baby was never actually his and blah blah blah.  Do you see how convoluted this is? That's the story. It is like a ransom stream of conscious thought. No planning or anything like that. The plot is really shallow.
