Need Help! Alchemy of Souls

My soul needs help! 😭💔I just finished Alchemy of Souls Season 1 and the ending might have thrown me into depression. How could they do that to us? Why? I kept thinking it was a dream(nightmare) sequence, like a warning premonition in Twilight, but then it kept going and was over. I can't believe that was the ending! This was setting up to be my favorite Kdrama and it was ruined! Did Jung So Min make someone mad during filming like Joey Tribbiani? Someone please make it make sense! I tried starting season 2 and that only made it worse. I can't move on to ship them.💔😭
