It would've been one of my favourite K-dramas, if it wasn't for Looney's ending. I've just finished watching and I'm sitting here just thinking about this ccharacter and feeling so upset.
It's like the writers let their own opinions about drugs cloud their judgement about what would be a good ending for the charactor. Looney worked so hard and long and got no redemption or happy ending. he had such great character development, until the last scene ruined it all. He was the best character too!
His story line just reflects Korea's stance of drugs. All other kinds of criminals got some redemption, exept the drugie.
It seems like the writers tried to send a message of "kids, don't do drugs" with his storyline. But instead they ended up sending the message that no matter how hard you try, once an addict, always an addict.
How disappointing!
