As is my R/martial arts tradition I will give my reaction with timestamps as i watch.

00:02 based only on the fact that the guy in white is dressed the same as the billion dudes in the background I'm going to give him the home field advantage.

00:05, they both almost identically kick, to me it looked like no sleeves got the better of it.

00:08, no sleeves keeps on attacking, no meaningful strikes landed yet.

00:11, they finally get into a flurry of blows. it is hard to tell for sure what landed where but it seems safe to say that their simultaneous chain punching while leaning back did not accomplish much. I'm wondering if sleeves will ever take the initiative.

00:15 the crowd starts clapping, I take this to mean that they really enjoy the caliber of WC they are seeing here.

00:20, more of the same kick/rush/back-peddle.
