Omg, this is sooo good! I love the story and the way it progressed, but if something could be more improved then I agree that the development of Yagi's feelings should have been more explored or shown (although I know that the story is not from his pov). Anyways, the manga is still great and that is a tiny flaw because we can still see even if it's just a bit of how and when his feelings changed.
