Background
The song talks about a relationship that is kinda tortuous, so regretful as pleasant for the singer.

The lyrics are clear but are enough open to be interpreted in numerous ways. One interpretation is about someone that went out, hooked up, and is feeling empty after that. Another one may be an interpretation for Rin's Love for Len and vice versa.

Although originally the song was released for Rin, it later Len's Version was well received becoming arguably more popular than the original Rin's version.

Though the song may have the same lyrics, how the song starts, goes and ends are different. Rin's version has her singing clearly at the beginning, then ends with her chanting. Len's version has Rin whispering in the background, before Len screaming and then the song starts. Also on Len's versions, his voice is remixed a few times and sings at a different pace throughout the course of the song, ending without Rin's Chanting.
