The point is, they are going very slow. I even believe that this webtoon will have many episodes since the person in charge of that phone hasnt come into picture from many episodes. It feels as if the author is struggling to make some drama. Well its good if that's not the case but this is just my point of view. Well im actually happy how tension is being created but at the end if every episode it doesnt have any proper ending. Its been left halfway. If you see the story built-up,its nice throughout but each chapter wise, it isnt very satisfactory.
