HOW MANY TIMES LIM SOOHO COULD'VE USED EUN YOUNGRO :
- sooho could've taken youngro along with the northern agents in the last ep.
- sooho could've used youngro as a shield in the last few minutes so that those swat team wouldn't have shot at him.
- i mean youngro has no family left anymore, so atleast she could've depended on sooho if he took her along with them, GODDAMNIT.
- also when youngro returns, they could've gone out the same way youngro came and joined ms.pi and lee gang-mu. you may that the swat team entered thru there. but they had enough time and lee gang-mu and sooho could've easily taken those swat team down.
- isn't sooho an veteran agent?!! how could he leave huge trail of blood along the way?!

PLOTHOLES:
- what happened to comrade kang after she left the port?
- did comrade kang go north korea and save the other agent's families as she promised sooho?
- and after that did she live happily in another countries?
- what happened in NK after the whole election scheme was leaked?
- what happened to choi suyreon?
- they showed us ms.pi and kye boon-ok but what happened to the other roomates of youngro in room 207? and also their boyfriends?
- who was seol-hui's father?
- what happened to man-dong's son?
- they showed us what happened the bad 3 and their wifes but what happened to their posts? who's gonna takeover?
- also they should have shown us if youngro makes up with friends, or if she vists her brother's grave?
- also what happened with sooho's body? is cremated or buried alive? or shown to public (publically shamed) or what else?
- what happened to suhui?
-many more....

*i still can't digest the ending even though i excepted but with these many plotholes how can finish this kdrama?!!
p.s also is my side couple over?!!
