Would be funny as hell if the big reveal happened, and the mc is just like “meh, ok. I already fell in love with another girl, but the mystery was fun for a bit.”
The pacing of this series is exceptionally off. I can't quite grasp it, but it feels somehow random or like it lacks something.
Hope it improves with the next chapters.
Wouldn't be surprised if there was also a sixth one; one the very first chapter, the first two girls we saw were not part of the mental quartet: a quiet tomboyish blonde and a vanilla friendly gal.
