did this ever release??? i haven't found it anywhere to purchase
@jakegaslamp @riipah yes, and tragically, it seems to have been a suicide, which makes it even more heartbreaking
I doubt that there's something wrong with the translation of the name for 厨娘 actually means "a girl who cooks well" in Chinese. Yet I don't know whether it's proper or not to translate it into "Magical Cook".
She said she didn't use Luo Tianyi in this song.
This picture seems to confirm a 2014 release at least.
@goldenchild: since the cached crossfade title still says VoMas 29, it means that the album was scheduled for VoMas 29, but it was delayed, or it came out at VoMas 29 and was re-released at VoMas 31. Likely the delay, but can't be really sure.
