I don't get it???

In the first few episodes, I was so hyped to see a female lead with a strong personality. It was also funny at first seeing the male lead have those breakdowns over having a crush on the female lead.

It's a running theme for old kdramas:
Why make a strong female lead and then make her fall for a jerk with an indescribable ego?

I didn't like how draggy it got after episode 8. The characters were literally just running around and having a minute or two of a crying session and what do they not do? They don't resolve their problems. And the way they do resolve these problems are just not convincing?

This was like BOF's sibling but watered down.

What made me continue watching? The actors. I absolutely loved the main actress. She delivered her role well. Lee Jong Suk with that emo hair and showing his pipes will forever be ingrained in my memory now. Hyun Bin? Not the best but he did the body swapping convincingly.
