A few years ago a Korean singer wrote a song about the sunburn mark that he found on his finger after he broke up with his girlfriend and removed a ring he had been wearing for a long time. This is the story that inspired him to make “Inner message ring”, a ring with hidden letters on the inside. When you wear this ring, after a while, the message will imprint on the wearer’s finger. The two messages here are “marry me” and “always”. Good idea!
