Yes, in my opinion the side stories aren't even "side" stories, they just continue chronologically after chapter 75. Chap 75 didn't feel like an ending in the first place, and there's like enough of these "side stories" to make a season or two. The end of the side stories has a nice finish to it too, one that feels like an ending.

guys can someone tells me if these side stories are after the end of the story?
cause the sides of kwon yuri are flashbacks so i'm kinda confused
