Poe had always wanted a soulmate in so long since he's always so lonely.

The red string/thread of fate is connected by the soulmates' pinky finger and means that they are designed for one another.

Poe was out shopping for new novels with Karl on his shoulder and felt the red string of fate tugging him forward.

When Poe looked around and scanned the entire area, he saw it.. his soulmate in the distance..

Poe's heart was beating so fast that he didn't know what to do at that point.
