Soulmates exist. When one turns a certain age they gain a red string tied around their index finger that only they and their soulmate can see, the other end of the string is connected to the index finger of their soulmate. Redson's string had been slack for ages now, he just assumed he didn't have a soulmate. Until he bumped into you, that was. You and Redson's strings are connected. You and Redson are soulmates.
