I am starting to think the head nurse was in love with MY's dad, and tricked him into killing his wife out of jealousy. While actually it was her that killed ST and KT's mom. That's why she was crying at his death bed. MY's mom wouldn't do that if he really tried to kill her?
I understand that the FL had saved our ML when he was young but that must have involved time travel right? cause…
Her police tag says date of birth 1990, and it happened in 1994. So I guess something with time travel. But I don't think it's her who saved him. Seems like a man to me, too tall to be her! Also, Yi Rim and Yi Gon both have a piece of the flute, but only Yi Rim hasn't aged. So I think maybe they don't age when they are in the universe they don't belong in?
I think squid fairy was kyung’s brother (And hier of the throne) in Flower and they all became aware of themselves. Haru was forced to kill Danoh on stage by kyung. But squid once said to Dohwa that it’s only possible for Danoh to have such a cruel fate in secret because she’s an extra. But in flower she was the main character... So Kyung changed the stage out of jealousy. He switched squid’s wife/lover with Danoh somehow. So instead of killing his brother’s lover (an extra) he let Haru kill Danoh :(
