after the 30th chapter or so the main love interest cucks MC hard, even though everything untill that point was leading to them developing mutual feelings for each other, but then suddenly out of literally fucking nowhere this shit happens. The author was constantly giving hints about them ending up together, especially when her kid accepted MC as a father figure, but no, the MC just had to blueball himself like a complete moron in the end. Some people would even try to justify this like the fedora tipping was a natural thing to do, but don't be fooled, it was just rushed and out of place, nothing else. People just try to cope.
