I think my comments are definitely not as insightful as econmtl's analysis but I still wanted to write down some thoughts.
Heungkuk players were kind of asleep in the first set, apart from maybe LDY who seemed very alert and quick from the get-go, but both LJY and KYK looked really off in that first set and Diouf just fired the spikes over like there was no tomorrow.
KYK woke up in the second set and really won that set for Heungkuk with help from LDY, she fixed several bad receives that went over the net and immediately got blasted back at them by blocking/deflecting them. Towards the end of the set she saved two Diouf spikes, one with her face lol.
LJY also woke up in the third set while KGC completely tilted of the surface of planet Earth. LDY even got one of her signature dumps in as well as one block. The rally before that block KGC Coach video-challenged a alleged net-touch by LDY - it turned out her ponytail whipped the net while she was turning after blocking (this has happened before, just recently)
Her reaction to the video-challenge:
Well at that point the score was 21-9 and the set was pretty much done and dusted.
In the fourth set KGC fought again but ultimately couldnt overcome the now fully-awakened Heungkuk, atleast not with just one threat - Diouf.
Heungkuk really made it more interesting by throwing that first set lol and then absolutely whacking their opponents 25-11 in Set 3.
At the end I really thought LDY would get Match MVP, after all she scored 6 points - 3 attack points/dumps, 2 blocks and 1 service ace, but it ended up going to KYK which I am also ok with, after all the W is all that matters and KYK looked very strong from the second set onwards.
Thanks for coming to my TED Talk.
