This was a wonderful story that went way too long and has a very sudden and unsatisfying conclusion, especially for a supernatural slice of life. I wish I liked it more, but it was 40 chapters too long.
The characters are what I enjoyed the most in the series, especially how they don't feel flat. Bambi is a complicated 18 year-old that really feels far older than he his. His complicated yet interesting thought process combined with his struggle with speaking his thoughts and feelings intrigued me throughout and made later moments far more interesting. He is kind to those he cares for and oblivious to anyone else, but his love isn't binary. The spirit Ako-chan sees this during her time with him, yet she fights with feelings of guilt for bothering him and worry about how to benefit him. She has a strong personality at times but is very passive in others. I like her, but sometimes the line between complex character and indecisive author blurs too much. She is sweet and is her own person, but I don't think she would work well without Bambi at her side. Most of the other characters are well-written as well, but I do find Yamashiro being far less important than she should be, considering the story.
A writer struggling with creating a new story meets a mysterious spirit in his newly acquired haunted apartment. Ako's connection with Yamashiro is interesting, but I think a big flaw comes from this. The back and forth of their relationship and what will happen with Ako is interesting at first, but it becomes frustrating as the rhyme and reason is lost. One chapter will say one thing will happen, but then the exact opposite will be told the next chapter or so. The only thing worse than the indecisiveness of the author is how unnecessary the length of the story is. If 40 chapters were removed, I think the story would be far tighter and less dragged out. The conclusion doesn't help, as it is a jump in time measured in decades to wrap up the story without having to actually write a conclusion.
7/10 I enjoyed the story a lot, but that enjoyed lessened as time went on. Luckily, the side characters and stories kept things interesting enough. I recommend considering it, but the plot is slow and sometimes feels like it lacks progression... And a weak conclusion makes a whole-hearted recommendation impossible.
