I mean, I do like them and it's nice to see how things progressed with the memory loss but idk, I just feel like they detract from the conclusion of the main story.
It was a beautiful ending how it mirrored the official start of Dooshik and Jooha's relationship with each other. It didn't really feel like side stories but as a part of the main story but told out of order?
Maybe I'm just picky on what I'd consider to be a side story ¯_(ツ)_/¯
