In the town of Trebuchet, there lived in the clock tower a lonely old poet - bitter and remorseful. Towards the end of his years, he composed a series of letters between an imaginary love interest and a projection of his younger self, and then locked them away in separate cabinets. He never opened those cabinets til the day of his death, fearful that his fabricated romance would disintegrate if the letters ever came together.

Ultimately the old man died and his personal possessions were cleared from the tower. The letters he wrote were discovered by the renovators and discarded in the basement furnace. As they burned, the raw emotion contained in them was released into the air and settled on a pile of old clothes nearby, animating them with the characters of the fake letters. The old man was just that pitiful that it gave the story powers to do that.

Anyhow, thus were born the young man Deegan and his sweetheart Sanpi. Because the true author of the letters they were born from was the same person, the two of them shared the same heart and were drawn to each other. However, for the same reason, because there was only one heart (and perhaps because of the old poet's lingering wishes), only one of the two could exist at a time. During the day Sanpi would be the vessel for the heart, and when night came she would turn back into a pile of clothes and Deegan would take his turn as the next vessel. In this way they continued to look for each other without ever knowing what the other looked like.
