Not My Fault is a collaborative studio album by South Korean music producer Dress and singer-songwriter Sogumm.

Sogumm's vocals that pronounce words differently are sometimes innocent("I Wonder", "Honey Bee", "Pretty Bitch"), dry("Sorry", "Once Again"), or magical("Diary", "Dreamer, Doer").

It tells the direction of the album with a down-tempo beat played with an analog drum set and piano, string, and guitar sounds distorted by an effects unit.

According to Jeong Byeong-uk, Dress "knows how to use minimal sources in the right place and bring out the maximum amount of dreamlike atmosphere and groove."

Also, Sogumm "pronounces lyrics uniquely while reducing the resonance of the sound and shows her individuality with unconventional breathing and accents."
