You may like or may not like them together, but objectively Rin is the best girl for Shirou
The routes' endings speak for themselves and the main battle within Shirou's ideals isn't UBW for nothing...
I really do think that ending up with Rin would be the best thing for him
When you think about Rin or Saber I'm pretty sure them wearing these outfits come to your head, but what is Sakura wearing in your head when you think about her? 🤔
