Emotional duo MIND U released their new single on Dec. 20.

MIND U unveiled their new single "Wrong Number" on various music sites at 6 p.m. on Dec. 20. This is the first in about three months since "I Tried" released in September.

The single features a total of two tracks, including the title track "Wrong Number," and the song "Lonely Winter," filling the album with music that can properly feel the sentiment of a calm winter.

The title track "Wrong Number" was born from the idea of "Have we ever regretted everything for our future, which was a distant, yet brilliant one?" and is impressive in its lonely, mournful vocals on lyrical melodies that give us deep resonance.

The song "Lonely Winter" was made with the wish that a little warm heart could be delivered like the midwinter sun. To celebrate Christmas and the end of the year, the warm but warm voice melted the warm and sweet atmosphere.

This time, Godak, who is also in charge of producing MIND U, participated in both writing and composing to improve the album's completion, while vocalist Jae-hee also added to the song's appeal by adding strength to the song's composition.

Based on this, MIND U will carry all the emotional music in the single, from the song of affection after the breakup to the song of warm and tender love, to convey the emotion to the hearts of the fans.
