On November 12th, singer-actress Goo Hye Sun released her 7th digital single “Must” (“Must I die?“) for the OST of her new movie ‘Daughter‘, which will be premiered on December 6th.

It was revealed that Goo Hye Sun personally composed and wrote the lyrics for “Must” with the featuring of Choi In Young. “Must” has a slightly different feel and melody compared to her previous works as it expresses a painful parting that is portrayed in the movie. Her light, angelic voice fits well with the emotions of the character.

The upcoming movie ‘Daughter‘ was also written, directed by talented Goo Hye Sun. She will also act in the movie, which tells the tale of  the complicated relationship between a mother and daughter who wants to come out from her mother’s shadow and find her own identity.
