Girls' Generation's Taeyeon has dropped the mood sampler for her comeback album.

The mood sampler introduces a series of powerful words centered around the album’s theme of reflecting on a past relationship. Named 'To. X,' this 5th mini album talks exclusively about bidding farewell to an old love and meditating on the dark aspects of the relationship.

With her own voice, Taeyeon remarks in the teaser: "My daily life has been entirely tailored to that person."

Taeyeon's new album will be out on November 27 at 6 PM KST.

What do you think of this concept?
