Urban legend states that two bodies that share the same soul also share their skin. As a kid Changkyun would hear that legend from his mother and since then always wrote little notes on his arm hoping his soulmate would one day see them. He was now much older but the habit remained a daily task despite being a very busy scholar. In the same town, in a busy tattoo parlor, a handsome artist who refuses to get tattooed, always had his arm littered with little notes from his soul bound.
