When I first watched Last Friends, I didn't feel great at the end. I wasn't sure why, but now after rewatching, I know why!

It's all about friendship, friends who are ready to do everything for their friends. As a 'friendship guy', I was supposed to enjoy it, however, I ended up with a bitter feeling. The reason is that despite all efforts and sacrifices, they can't really come closer emotionally to each other, so in the end, they still live their own distinct lives. And this is more obvious in the relationship between Michiru (Nagasawa Masami) & Ruka (Ueno Juri). They're supposed to be best friends, even more than that, but from the beginning to the end, they are clueless about each other feelings.

So, a very good drama in depicting that friendship can fail big time sometimes, even if friends do their best. And this is not what we can often see in J-dorama, tending to show the magical side of friendship.
