Lemme just add that since her mother was out of it, she could have taken a while to actually realize what has happen, then she burned the building she was in with uhm the mother f*cker she married inside still
I forgot to mention this fact
(Also is it weird I like Elvis' vibe as well, I thought him and Yuju was a silly duo like friendship sorta duo.)
I don't know if I'm right or anything but from what I read in the comments I made like my own sense of the story(so like a theory in ways)
I think near the end the adoptive mother could have hired the kidnapper to kidnap Yuju and then off her(Yuju) , I then also thought that maybe the mother(adoptive) ,the guys friend and the mantis could have been working together, just for the fact the guys friend seemed to be included in this situation, maybe he put the hit out for the buff main guy and hired the mantis to do it, then maybe they sent the box with an already dead Yuju to the house and since the box was open maybe the buff main guy opened it cause he seen the nail polish design through the handle holes, this is what I think happened with his death situation, maybe he grabbed Yuju and was trying to go to a hospital to try and save her, but on the way he got attacked by the mantis which is how he died as well, and later later when uhm giju(? Brains blanking) heard they were dead he let his subconscious win telling him to jump off a cliff to committed s*icide, of course this happened cause the only two people he cared about had died. I'm guessing the subconscious was also his biological mother?
I'm not entirely sure
But that's what I think might of happened it doesn't mean it's what was actually happening but just a thought, sorry if it doesn't make sense and has a ton of mistakes I was half asleep writing this, (I have more of a creative when I'm half asleep)
Ahem anyway
