my initial impression on this drama are all good. characters are good especially the ml, a sometime goofy nonchalant guy but get things done. story so far is good, they kinda hinted who the bad guy(s) is but not the villain, not reveal the whole plot in 2 eps and keep the viewer in the dark is a hint the writer know what they are doing (ive been so disappointed with a lot of korean thriller drama lately because of this issue). also like how the victim arent just some powerless people. the pacing is also good, they just reveal enough too keep the suspense up and not many filler scene and the flashback at the start of ep 2 is something i dont see often in korean drama. im gonna expecting a lot from this drama.
f8ck logic
wait i think the later case would work well with how the system work if it use the last updated time.
