if you want to compare muscles, we won't be able to compare with western people and African people
Kpop is not girly, if you want to say it is girly, then if Kpop can make girly guys attractive to western girls, then it is an achivement, coz naturally, asian people can't compare body muscles or size with western guys.
Science is just one kind of soft power. Entertainment is another kind of important softpower.
Look at how many people go to South Korea for tourism, cosmetic or even plastic surgeries. Actually Japan has better plastic surgery tech, cosmetic and tourism environment, these are actually shortcoming of South Korea. But south korea make it possible that it is more popular in these areas due to Kpop.
and South Korean people are actually bad-looking. I watched some episodes of Korean dramas, the actors are not so beautiful as actors in Chinese dramas. But they are popular in the world, while Chinese dramas are only popular in some Southeast Asian countries, and mostly not modern dramas but ancient costume dramas. South korea can turn their shortingcomings into advantages. this is soft power
