I love this so much. It makes me feel something so nostalgic yet so fresh..
It felt a tiny lil bit rushed in the end, but just a little thinking was enough to put what was missing in it's place, so no big deals.
I'm really slow so it took a minute after reading the chapter to notice that , after leaving, her dad was the one to call Beniko.
Hearing about the girls in love who commited suicide was what placed the last pieces of the puzzle for him.The confirmation of what he already knew.
Now certain that his daughter was in love with Beniko, he preferred "losing" his daughter by her "running away" with the woman instead of the other option. In the end he realised he loved his daughter enough to go against himself... kinda like how Yuki was ready to confront her father about her "forbidden love".
I may be wrong with many things, but I really like to think this way ...
