I personally don't like the pace of the story, how complex is it from the start, and how many characters were involved in this story. But, at the end of the day, it's a heartwarming and tearjerjking story. the twist is there to make you surprised, to make you emotional, and then feel so much relatable to them.

to put it simply, it's life. things changes, but we never know what change it. when it changes, then we feel silly for the reason it changed.
