we finally get significantly more romance and its more bittersweet compared to the other seasons although this might mainly be because its the end of the anime
its just as confusing (to me at least) as the other seasons but thats not a bad thing
its the final season so i dont see any point to put off watching it if u seen the first 2 seasons already
the ending is great not just because of the (slightly melancholic) satisfaction of reaching the end of the story but also because of the mixture of emotions it conveys not only through the story and events but also through the characters (specifically the main 3), you can feel their emotions clearly and can almost sympathize with the characters too, leaving you with a mixture of emotions yourself by the end, which is what makes the anime so good in my opinion
