Best Friends To the End

Hello. After seeing the ending of Alicization, my heart was broken enough already. But to see the ending of Crisis Core in that same way? IT'S ALREADY TEARING ME APART!!! Other than that, I saw how Cloud and Zack's relationship was almost similar to that of Kirito and Eugeo's. So I thought I should add a little comparison between the two. At the moment, I couldn't find a happy moment with the both of them, but I promise I'll add in nicer comparisons where they're both happy.
