This manga is just the usual nonsense about a dark-haired heroine being a helpless melancholy girl who needs her mc to save her from everything.
Utaha was a professional with ambition in Girl Side and in the Saenai anime. Here the author turned her into the misogynist ubercliché of the melancholy dark-haired female author who doesn't know how to communicate and needs others to do everything for her.
In Saenai Girls Side (which was so much better than this it's almost beyond comprehension it was written by the same person) and the even better anime of Saenai Utaha didn't get much acknowledgment either, but she was at least portrayed as a human being instead of a clilché that only serves to fill the story with boring trope ridden plot. In Saenai Girls side she was interesting and engaging. She showed strength and together with Iriri was actually moderately innovative as a character.
In this story she is the boring trope ridden moe-slut serving center of a horrible trope-ridden story that didn't make sense most of the time and was all over the place. If I could protect people from wasting their time on this disgusting, boring garbage I would.
Watch the anime for Saenai Kanojo instead if you want to consume something from this author. It is at least worthy of your time.
