I agree to everything mentioned above. Especially about the shaman's son. I get that he was used as a plot device, but it is so lazy to just throw out the son's character as a whole. It's like he never existed.
Also because of the rushed ending, the romance felt very forced and because they didn't develop it over the course of the show, I feel like they should have just stayed as friends instead. The FL never seemed to be attracted to ML at all, infact she straight up hated him, so it was very stange how suddenly she fell in love.
Oh and also, did everyone just forget about the detail that her hair falls out every time she uses her powers?
