Can domone explain yhe dark secret?

The dark secret is that when they were little kids, one stormy night, when seme's mom and dad had locked them in the black room. They wished that the parents would disappear leaving them alone. And their wish came true, their malicious wish got too dark and took a physical from inside the mirrors. Then the hands came out of the mirrors to the real world and killed the parents. After that their malicious form lived in the mirrors and seme learnt how to use the power but uke lost his memory so didn't know the whole truth until the end.

Did they die? B cuz they're saying the memory los A.K.A the side storys happened before chapter 90 or the last one, chronologicaly? Help me I'll belive it even if it isn't true

Spoilersssssss: nope they don't die. Memory loss happens at the end of main story (ch 90). The side stories now show what happened after jooha lost his memories. he then regains his memories (when they fell in the ice; they will survive) halfway towards the end of the side stories. So basically some parts of the side stories are just extended and repeated parts seen in ch 90.
Raws pleas
