I thought the ending was utter crap.
SPOILERS AHEAD:
Two tired k-drama clichés one on top of the other: Noble idiot and time gap without any contact.
Then he comes all cocky and confident, smiling and pinching her cheek patronizingly, with a background of funny music. What happened to the reasons that turned him noble idiot? Something changed and he decided that “naah, that was all BS, let’s go back again”? And she accepts him just like that?
I hated, hated this.
And the poor timpanist? Why did they give him such an ending, out of the blue?
And manager Yun, how did she manage to dodge the responsibility? Who was punished and how? What about the Chairwoman?
Extremely sloppy writing there.
