Okay so hear me out, Bum at one point promised Sangwoo, that if Sangwoo died Bum would kill himself too. And at the end, we see the walking light change. So can we assume that he is dead too?? Like a little fun note. I kinda like this thought better than him being haunted
So no ones gonna point out that Sana pointed at women through a glass and said “SiO2”. She literally called them plastic (silicon but still)
She pointed the glass before the mannequin model . Glass is SiO2
