LoveMeter

The LoveMeter was a tattoo-not just an ink tattoo but a scientific one that was etched into the skin of the wrist of every person. The sole purpose of this tattoo was to tell the person whether their soulmate was close by or how far they were from their soulmate, in terms of distance.

Now the LoveMeter was about to do its magic and tell Lee Donghae just how far he would be from meeting his own soulmate.
