Yeah, modern Kaguya really does struggle with these things called 'emotions'. This is her second chance, and there is still time for her to realize the power of love, and the importance of the actions of her past self in the grand scheme of things.
Maybe this second chance is her reward, in a way.
Also cute that Kurenai, potentially reborn Shizuka, is the one helping her realizes some of this here.
... and a curious chapter sequence going on, here... 208 is in the next volume, after 209. Welp, not the first time, guess I'll just accept it.
