You can say ''True ending'' as it was in the last chapter of the manga.
I think i am not the only one who left with some kind of a ''Hole'' after the series , and this OVA really filled that hole. And made me my day happy.
Also it was great that other characters and some diary owners were brought back. And some humor with Mao-chan and Hinata was great !
I'm happy for Yuno and Yukki :)
