Labn, an innocent little Shou (mistaken), wholeheartedly waited for his lover. Because of a car accident, he became a soul wandering in the world, looking for his lover Tren, but he didn't know that Tren was dead.
Tren, the culprit who bent Labn (by mistake), was afraid that Labn would be harmed, so he resolutely chose to leave and then died quietly.
The priest loves Labn deeply, and he is an important matchmaker for Labn to find Tren.
