Honestly it depends on the person who is using the power otherwise every power is super special in their own way, still if I have to rank then Lee Mi Hyun's supersense power seems the weakest while Jeon Gye Do's electrical power seems the strongest (Again, depends on how someone uses it)

About the superspeed power, I don't think Kim Doo Shik has that power, my best guess is Lee Kang Hoon and his mother (or father) has the superspeed power

Also about that 'Second string', my best guess is they are experiment subjects. That's why they aren't strong enough like the originals

I think there were more songs but Thank you so much

That may seem like it cause we already know many characteristics of zombies and expecting any moment the zombies will come out. But when you are in the real situation like in this movie where all of a sudden a threat comes towards you while you were minding your own troublesome life, you ought to make dumb decisions

Obviously deserves more than this.

I was talking about all the songs in his playlist

Can anyone tell the song list from Bong Seok's cheer up playlist (Ep 6 or 7)? I really can't see it clearly

I have some questions,
Who was the girlfriend of the stepfather shown in the pictures in the last ep? Do we know her?
The MC didn't get any punishment for drug usage and drunk and drive or they just didn't mention it?

They mentioned who the real killer is in the last episode. If you wanted to show of the real killer going to jail or being interviewed then that's not important. It's pretty obvious what will he say and what will happen to him so they don't have to show it in a 8 ep series.

Yes, it was dissolved in some narcotic solution

Same. In the end I had to use Auto subtitle generator.
