Only reason this one got higher than 5 is because I respect Hachimitsu Scans. An MC who literally couldn't deal with a single problem (read: conflict) in the story without the help of contrived coincidence, characters introduced to artificially increase tension and create conflict with no depth and relevance to the narrative otherwise, 2 entire volumes of character development leading to "hey, let's stay exactly where we were at the end of the first chapter and make the entire story a complete waste of time"...? Yeah.
Some authors should really stick to oneshots with interesting premise rather than trying to milk as much story as possible out of some nice gimmicks with the hope that good art will carry the rest of the story.
