The movie was rather relatable in how lonely the character's life was lived however, I will say it did not feel like the movie picked up until the last 15 minutes, when she makes the call with Jina it really felt like it was going to go somewhere in which the character finally allows herself a moment to breathe and the angst and tension with her dad will be released however the ending is rather lackluster, I understand the character and her mindset, in fact, I am quite literally her, however, the film was making this large buildup with her father and the girl she was training only for it to fall flat. Although, she resolves the conflict with Jina, the one with her father feels unresolved due to the fact she doesn't meet up with him nor is she able to have an actual conversation with him about how she feels about her mother's death (a major catalyst for her break through on the phone with her dad). The ending just feels unfinished and yet way too long at the same time.
