Yup, definitely agree with the bias part. Despite his claim of saving-helping the world he lives in. He does not offer help towards other countries and focuses solely in Korea, though I understand this is fiction and will depend on the author. The lack of care or consideration with other countries is sad. The world tree showed him a bunch of humans that was being manipulated by Organa(? lol is that even right) but made no move to locate or investigate the possibility of where that was. ╥﹏╥
Remember, just like the premise of the story that has handed him everything technically and tells them exactly what to do. He’s expecting it to also just randomly be able to stumble onto it. Literally when the book came to him it was just given by a friend, which is lucky he did say it he did say that everything he has was technically just randomly handed to him and just because he was a little bit. Nice that’s it. He’s just the most basic ass man that they could’ve put in there. That just isn’t a a major misogynistic asshole that’s what they did. They just took that part out to make it more fluffy took like a lot of greed out of it, but I do agree. Most stories will just immediately not give a shit about any other country or the world itself they’ll just send her around the country of origin that it’s made around of a lot of American comics kind of do this but mostly they don’t. They always try to focus on the world itself, but a lot of Korean manga usually only focus on them like a superior people which is one part that I just don’t enjoy.

this is an opinion on how I see him.
He’s naive. Too soft. He leaves so many loose ends. He’s nosy and for the record he’s bias towards his friend instead of being neutral. for some reason it’s kinda hard to read as the story goes. His identity is so easy to see, the people of Gehenna immediately learn the he’s the gardener as soon as they meet. the Garden and the story has a nice premise but this feels like this kind if MC isn’t suitable for this kind of world building cuz he really doesn't understand his responsibilities. I kinda expect him to atleast understand know how a civilisation and human nature work, specially since he can see things from a gods perspective. tho I understand that he’s basically just a part timer since he is still human outside the garden but meh this kind of MC in this kind of genre and theme isnt MY CUP OF TEA so lets leave it at that.
