Wax has come back after 5 years with her new digital single "Coin Laundry."

On January 9th Wax released "Coin Laundry" on numerous online music sites.

"Coin Laundry" is a song that sings of wanting to erase the memories and scars of a farewell, just as a coin laundry washes everything away. Up to now Wax has sung of a woman's love and life, and there are great expectations as to how she will help all women relate to her new song.

The new song is the result of a collaborative effort of a composer/producer project group called Ember Glow. Ember Glow consists of rookie composer Hong Joon Suk and "The Calling" pop producer Billy Mohler.

Billy Mohler himself made an appearance in the flesh for this song's session. He contributed in the drum, bass, guitar, keyboard, and percussion aspect of the song through live performance.

Wax revealed the 2nd teaser for the music video along with the song through her official YouTube channel.

The 1st teaser revealed Daniel Choi and Son Soo Hyun's bag hug scene, which quickly became a hot topic among viewers. The 2nd teaser was expected to feature the couple in a heartbreaking light, with their emotional tears scene.

The complete music video for "Coin Laundry" will be released on the 10th, which is when Wax will enter full-scale activities.
