SM teamed up Woohyun and Key to make an inter-group subunit...all for the sake of brainwashing teenage fangirls into swallowing for their oppas. If love is delicious and nutritious, it doesn't take a rocket scientist to know that love was substituted for 'jizz' in the song. I think this is a great marketing campaign from SM, as it explains the virtues of girls swallowing oppar's cum not because of the taste, but because of the health benefits.
Despite how thin Koreans seem in contrast to us fat fucking Americans, obesity is a growing problem Korea. From OECD's own website, obesity among adults is less than the typical Western country, but the obesity rate for children is pretty alarming. Given South Korea's barely existent birth rate, South Korea will eventually become a nation of fat fucks like Western countries are today.
SM sought out to fix this problem themselves, using their best assets: young men who have millions of crazy teenage fangirls willing to listen to their every word. SM knows full well that SNSD can't promote for 50 years (since SNSD's contracts expire in 2047), SM needs the next generation of females to not be a bunch of fat girls. No one will be stanning 뚱뚱한 시대, so the problem needs to be tackled before it's too late.
In order to get females away from eating junk food, which could cause them to become fat if they don't control their eating behaviors, SM wants teenage girls to swallow their boyfriends' sperm by saying it's nutritious and delicious. It doesn't have to be factual, but this method deters girls from gorging themselves with Twinkies.
Fucking genius, SM. Fucking genius.
