This ending was good, but it was too underwhelming for my liking. It was all a dream? then MC sees his dad again who is pathetically sad (he failed the life he chose) and we see Daisuke become a successful writer (dang so it wasn't a dream). I wanted to see MORE of the MC's aftermath (How is Tomoko, Masao, Takashi, etc.)
I hated how the MC treated Tomoko in the end, I get the MC was in his feels, but he was being a little TOO selfish no? granted he probably was never interested in Tomoko since he had a wife and kids, but he still went about it the wrong way.
Glad MC finally understood why his dad left, it's cool that he learned about family lore, and the dad leaving was the realistic fate. The problem was never the MC or the family it was himself.
