Chemistry

At first the ML is way too aggressive / a major jerk, but in the second half of the drama their chemistry is pretty incredible. 

I found the ML to be very unlikable in the first half of the drama, and much more likeable in the second half of the drama, which is when their chemistry takes off. 

There are some awkward moments mainly due to the love triangle, but some incredible moments too. The hot spring scene along earns them a place in this list. 

Fantastic chemistry in the first half that fizzled in the second half.
