Well then...
Kwon produces a lovely sliced passing shot to snaffle himself a break point.

Novak Djokovic's concentration is definitely in and out to say the least - 1,005 matches he has won as a professional, he has dealt with these situations many times before.
Djokovic is really not terribly engaged in the contest, he's struggling to find the inspiration to get through this awkward opponent.
*Djokovic 6-3 3-6 2-2 Kwon
Both players miss a pair of forehands but Djokovic thinks he's wrapped up a hold to 15 with an ace down the T.
He challenges after a very late call of out... oh, and it is out! Back to the middle he goes and then suddenly finds himself at deuce.
Hmm...
One of the guests in the Centre Court royal box today is Ukraine's ambassador to the UK, Vadym Rystaiko.
There are also representatives from the Polish Family Association - a charity supported by the Wimbledon Foundation caring for Ukrainian refugees arriving in Poland and the UK.
Their attendance comes a couple of days after Ukrainian former tennis player Sergiy Stakhovsky, who reached the third round at Wimbledon in 2013 and 2014 and has been defending his country since it was invaded by Russia, tweeted this:

*Djokovic 6-3 3-6 2-2 Kwon
Kwon Soon-woo's support box are absolutely loving this.
They rise to their feet and applaud as a clean forehand winner helps their man along to a hold.
Djokovic 6-3 3-6 2-1 Kwon*
That's exactly what Novak Djokovic would want - a speedy hold to 15, wrapped up with an overhead that lands nicely inside the court.
Organisers have just confirmed there will be no play on the outside courts until at least 15:30 BST because of rain.
British number one Cam Norrie is on the brink of victory on Court Two but will have to wait for it.
*Djokovic 6-3 3-6 1-1 Kwon
Kwon is doing an awful lot of retreiving behind the baseline and benefits as Djokovic comes forward and misses another forehand.
There's been no real reaction from Djokovic so far, but that's a bad miss on an overhead and he knows it, helping Kwon along to ahold.
Djokovic 6-3 3-6 1-0 Kwon*
Kwon is a little too casual on a slice backhand, sending it out of bounds to slip 0-30 down, before Djokovic hangs his head as a forehand goes long.
There's still a chance for the defending champion, though, but he twice fails to put away overheads and then ends up skewing his backhand long.
Djokovic challenges but he knows it's long, and it's 30-30.

There's a real buzz around Centre Court now - but that may also be the rain bouncing off the roof...
A rumble of thunder overhead is followed by chatter among the crowd. Everyone's looking rather glad to be sheltered in here - especially now we have a real contest on our hands!
Djokovic 6-3 3-6 1-0 Kwon*
A long forehand from Djokovic keeps this game going a little longer than he would like, but he holds to 30 courtesy of a long forehand from Kwon.
*Djokovic 6-3 3-6 0-0 Kwon
It is, to use a technical term, absolutely hosing it down at Wimbledon.
The rain is splattering down onto the roof on Centre Court as Novak Djokovic serves to start the third set.

In case you missed it earlier, Britain's Jodie Burrage rushed to help a ball boy who was taken unwell during her first-round defeat at Wimbledon.
Burrage raced over to the fridge for water and got an energy gel from her bag when he was struggling early in the second set, later handing him sweets while he sat on a chair.
The 23-year-old watched over him, talking to him for several minutes before medical assistance arrived.
The boy was helped off court 18, walking shakily, before play resumed.
*Djokovic 6-3 3-6 Kwon
That was terrifically entertaining - and Kwon showed excellent grit to serve that second set out.
Djokovic had his chance to get the break back but squandered all three opportunities.

I certainly didn't expect this but Kwon Soon-woo absolutely deserves this second set - he's been aggressive and when the big points have come he's the one who's come out on top.
Game on.
Djokovic 6-3 3-6 Kwon
Well!
Djokovic 6-3 3-5 Kwon*
What a wonderful drop shot that is from Kwon Soon-woo!
Set point!

Uh oh! There is a groan amid giggles on court two as another rain shower comes out of nowhere.
Awful timing for Norrie, who was aiming to close out the win.
Brollies pop like Usher's collar, covers are dragged over quick sharp.
Djokovic 6-3 3-5 Kwon*
What a brilliant bit of running that is from Kwon, darting forward to reach a Djokovic slice that took a bobble off the net, and he benefits as Djokovic nets a forehand.
Wallop! Big forehand from Kwon after a lengthy rally and we're at 30-30.
