well the original makes sense if you actually read the manga but wathever
i don´t really like this alternative version because cuts off one of the most important parts of nanamis personality
the fear of being tied by someones love and expectations hence why she loves yuu beacuase she can´t love her back (at first) yet she is so kind to her
so she just acepting yuu feelings like that makes no sense and make pointless 80 % of the manga that bluntly tells you about all of that but again than only would make sense to you if you acutually read the manga
