Fan death is a widely held belief in South Korea that an electric fan left running overnight in a closed room can cause the death of those sleeping inside. All fans sold in South Korea come with an automatic timer that turns the fan off after a certain number of minutes
Wiki article http://en.wikipedia.org/wiki/Fan_death
this is just a joke about the fan saying "you win this round" as though it wants to kill South Korea
if anyone wondering why the picture looks so dark I put a filter over the drawing to make it look like it's nighttime (I used the marker fill with black color)
