Subjectively some might think that JiWoo won because even tho he got incapacitated, he was able to land a fatal blow to SiWoon enough to damage his core.
But if we're talking about the rules, it's an official spar, if one cannot fight anymore or incapacitated then they automatically lost.
Doesn't matter what happened to the fight or how much damage each was able to land, last one to stand wins.
This is from me, a major JiWoo fan.
Idk abt the west school culture but their antics are so asian coded
