it was well produced, well acted and high quality content but I felt the plot and the process were lacking and draggy, and I really hated the inconsistent ep lengths xD (also the way they didn't sub the texts, I deducted 0.5 for that!)

throughout watching this I heard things like "omg that was unexpected, everyone should pay attention to every detail or you'll miss everything" and well, it wasn't that unexpected and I also didn't pay that much attention to the side dialogs but I missed nothing ;D


it's like there are a few "twists" that can happen
- 1 or more of the mains were a figment of someone's imagination
- the story was a "what if", what if the teacher killed his in laws, what if the kids sent a letter, what if he didn't open the door, what if the sister died
- maybe "Yan Liang or Zhu Chao Yang" are actually the teacher's past self
- one of the kids will end up as a psychopath and kill someone

and so forth. and that's why I dreaded it, but it was actually a reversal, one of them did kill and it had nothing to do with the mind games of the teacher.
it some ways Zhu Chao Yang probably pushed his sister becasue he saw the teacher do it, and so everything was indeed a domino effect but tbh there were many many times I just screamed "they should tell the cops!"

they should've told the cops right away, their intention was never the money they were just too naive to write a "warning letter" to a killer telling him to live the rest of his life without killing.
pau pau should've told everyone about Zhu Chao Yang, she shouldn't have bullied the kid.
they shouldn't have blackmailed, they should've told the truth when the creepy uncle came about....

it's kinda like death note, at a certain point one wonders if they should root for the 1st main becasue they are usually the "hero" (not root for his murders but like after he lost his memories I always wondered if he's supposed to be "good" again ;D) and the kids were fragile and easily breakable.
before pau pau and Yan Liang, Zhu Chao Yang was an outcast, his dad never paid attention becasue he had another family, his mom worked hard to earn money while also hoping for a life of her own, and Zhu Chao Yang thought he could break away and gain their respect if he studied hard but everyone just hurt him more

so like I get the "thought provocativeness" of it but I do think they had too many filler scenes, yes I don't pay attention when I get bored, but attention is earned not given. if something is done well enough to grab my attention then they get the right to be called a 10 storywise ;D

I never rewatch stuff so ;)
