medical wedding (vocaloid)

A lost masa works design song, a 10 second NND clip of it can be found here: https://youtu.be/2yZwVqGgLzw?si=SFu5WKq03oGpNOWY

Not much is known about that song. Some theorize that the song is about GUMI, a newlywed bride who promised her partner to stay with them until the end. Unfortunately, GUMI's partner falls ill and is about to die, so GUMI slits her wrists open in order to die with her lover.

Others believe that it may have been about GUMI about to lose/has lost someone she married, proceeding to attach some of her partner's parts to herself.
