For what it's worth, I think the last 3 or 4 episodes are worth keeping. Strangely, there's a preview box at the end of 163 and 164 that has nothing to do with 165. Actually, it's a postview box.
I'll miss the show, but I won't miss the incessant laughing and giggling after almost every sentence:
"Hello. HA, HA, HA!"
"How are you? HA, HA, HA!"
"I think I broke my finger and my dog died. HA, HA, HA!"
It was explained to me when I first commented about this that Koreans always try to put on a happy face, but I haven't seen this much excessive chortling in any other K-drama I've watched.
My guess is there was a continuous nitrous oxide leak in the studio.
