It's heart warming and breaking at the same time. It contains so much emotions and message wanting to be heard. Their relationship is kinda hard to describe at first, but they tried to make it clear between them as the story goes on which is good. As one tries to understand, one tries to express himself in a clearer way. There were only some points that if possible they could've dug deeper into to make it longer and more satisfying. It is indeed short but bittersweet. Nevertheless, it's good enough if you're looking for depression. (Jk lol)
