If you're not an ardent fan of Jung Hae-in, you would find the story moves extremely slowly at tortoise pace.
If the script writer has set out for an 8 episodes drama, i think it would be a success.
For 16 parters and then truncated to 12, the story was initially stretched "repetitively" to the extent of ho-hum-can-run-in-background-without-paying-much-attention drama and then weirdly speeded up to end was a disaster all
in all. Such a pity.
