Good things come in... pairs?

For some reason unbeknownst to me, Korean couples have the need to show to the public that they are a couple.  By that, I mean they show it in numerous ways.  In North America, matching jewellery is not uncommon, but I'd be hard pressed finding couples looking like these walking around in public:

There are also couple rings, couple cellphone accessories, couple PJs and more.  A couple ring is typically exchanged on the 100th-day anniversary.  They call this "couple look" and couples actually walk around like this on the streets.  I get embarassed myself just looking at these couples.  It's funny seeing the guy or the girl astray from his/her counterpart, because these couple shirts don't make as much sense without the other half.  

I, personally, will never be caught dead wearing these.  

See?  These people are so ashamed that they blurred themselves out of this photo.
