Although I also find this "getting together with my dead sibling's lover" trope to be rather distasteful, I think this manga does a much better job with this trope. Often times it can feel disrespectful to the dead partner and just feel like the sibling is a replacement. However in this manga, the ending is more open ended and the focus is more on Yukito trying to find happiness again step by step. It's clear they don't immediately end up together with the line "I don't have all the answers yet...just hope we can see the sunflowers together next summer". I felt this was a sweet story that did not harp on the "fucking my dead sibling's lover" but rather on finding comfort in the small moments and rediscovering happiness.
