STORY 9/10
I love mystery, thriller, and suspense so I very much enjoy the plot given, it gets interesting after a few episodes and the more we unravel their secrets the more shocking and interesting it gets. and I personally love revenge and school-related dramas so this is so entertaining to me. and I get to make conspiracies on why they're there and what happened it's enjoyable

ACTING 6/10
first of all, they're not bad actors, they're idols. I'll let that information slide
the acting is average, its not really wow but if you enjoy acting more than the plot this drama might not be that entertaining for you
but in a way, their actions may look a lot more realistic if this was in a real-life scene, it looks natural in my opinion

MUSIC 7/10
honestly, i don't pay attention to the music/soundtrack/ost
i personally don't like the ost, but the music they used in the drama really helps with the ambiance and situation they're in

PRODUCTION 8/10
I do think they put a lot of budget into this, I love the details on what's in the room and everything. they paid a lot of attention to it and I like it very much
the camerawork is ok, sometimes they put too many pauses and it makes it kind of boring so I had to skip some parts just to see more pauses

REWATCH VALUE 4/10
It's a good drama, but it's forgettable at some point.
won't be rewatching this any time sooner tho

OVERALL 6.5/10
I enjoyed it
