It's not trash,it's not garbage,and none of the character are unlikeable.
What it is,though,is a free flowing work,as the artist mentioned,touching upon plot points that are left in a manner that a longer run would mean actually exploring them,at this point,a task for the fans to who can,double points if one can somehow get an AI to get that scratch look out.
Ended nicely enough,was not a waste,but is truly a damn shame to be the only work the artist has made that is on Mangadex,not the recent butchering makes it easier to get more of the works.
