The report indicated that her family was profoundly impacted by the unexpected loss and requested that the reasons for her passing as well as other specifics remain private. They also urged the public to refrain from speculation and spreading rumors.

The memorial service will be conducted privately, with attendance restricted to family, relatives, and close friends, as per the family's wishes.

Mo was previously an idol trainee before she became the lead vocalist of Acoustic Collabo in 2019, performing alongside Kim Seung Jae.

Acoustic Collabo originated as a solo endeavor by Kim Seung Jae before vocalists Ahn Da Eun, Kim Kyu Nyeon, and Mo Soo Jin joined the group, as reported by Korea JoongAng Daily.

In 2022, the ensemble was embroiled in a legal conflict with its previous management company. Following the resolution of the dispute, the group made a comeback in 2025 and entered into an exclusive agreement with the agency Panic Button.

In addition, Mo pursued a solo career, releasing her single Your Universe in June 2025.
