Chinese media reported few days ago about Tyler Kwon and SNSD's Jessica being engaged with reference of their rings.
However, Tyler Kwon clears up the misunderstanding and posted a message on his weibo today, "Hmm, can someone please explain to me what part of "best man" was not clear? Also, how did my friend's rings become my rings?"
Along with his latest post is the link to his earlier photo of the 'ring in question' which turned out to be owned by his friend.
