I know I'm bias against harem but Rent a Girlfriend art is excellent but story-wise, it's just unenjoyable. Can't even force myself to read it I just want to skip to the ending. I feel like the author is pushing it with the length of the manga.
Just finished the story of Guilty Gear. I couldn't immerse with the general story but the more I got into a character, I just went down deeper and deeper and now I'm sad.
