The youngest girl group is making their debut.

On March 11, HR Entertainment revealed that a girl group with an average age of 13 will be releasing their first official digital album, 'I think I really like you.' Consisting of five girls, the girl group will be named CooKie and will be entering the music industry as the youngest girl group.

In particular, member Hannah has been drawing attention before the group's debut because she has been known to resemble Wonder Girls' Sohee and was given the nickname 'Little Sohee.'

On March 15, the music video for their debut digital single will be released, where the five girls will show off their various charms and put on cute performances.

An official from the agency said, "There will be some restrictions on the group's activities given their age and having to attend school. However, they are ready to perform on stage whenever and wherever."

CooKie will be releasing their single along with the music video on March 15, so stay tuned for more updates.
