Drama was good the 1st part blown my mind. I also think that there were some parts missing or kinda incomplete story or their were some loop holes to it . Like they havent show anything about the kids they rescued and woo bin. Also how they found there operation base themselves so that was a big gap there but bro acting, awesome I never left like watching a acted show. Good drama but the ending , uh killing em all was so sad bro ? that was totally unexpected like I was like uhh how they will end this a happy or sad or suspense with another season / part but it was totally unexpected broo ☠️ still I m happy I watched it the friendship they had, the bond was so ?
