Heartstrings

Just about everyone knows about heartstrings. Heartstrings are an invisible line that connects you to your soulmate. Once the line is cut they both die. The only way it can be cut is by shedding a tear of pure pain caused by the other. But what would happen if you didn't have only one heartstring? (I did kinda use the idea from SILVERKOOK's book Burnt. Check it out, It's really good!)
