Summary: Happiness > All of us are dead

I wished they got better main leads, i liked the supporting characters better (Especially the 2nd group of survivors , hari, mijin and the 2 guys) better than the boring main cast. The story was nice but nothing to rave about.
Some characters are just plain stupid like the mom of one of the main guys.
What i hated is that they just bombed the whole city instead of finding a cure.
The story as a whole is just very unclear on how the actual virus started and series just ended like huh? I wouldn’t say it’s a cliffhanger cause it’s not wanting me to see more episodes or another season.
