Crayon Pop Sub-unit Strawberry Milk released their Debut Song 'OK' music video through YouTube on October 14. Within a week, they have gained over one million views and many comments that describe the catchiness, cuteness, and excitement of their song and music video.

Strawberry Milk, comprised of twin sisters ChoA and Way, appeal to the public through their cute concept by their catchy lyrics that are easy to sing along to and the dances that are similar to Crayon Pop's "Bar Bar Bar" jumping choreography.

This time the girls trade out their helmets for strawberries in their hair and big straws on their backs while wearing pink or red colored clothing to portray a strawberry milk carton. At one point, they also wear dresses with the design of a strawberry and have forks on their backs while singing about how well the guy they are both infatuated with can cook.

This song is fun to listen to for girls who are in the mood for a light, upbeat, and bright tune.

The male character of the video has his head is covered with an "OK" sign. However, the sign fits into the theme of the song because it is a fun song about how the male character is the epitome of the "perfect guy" through his gentleman-like behavior, ability to cook, and longing for only one girl.

Way and ChoA were a logical choice for the first Crayon Pop sub-unit. Since they are twins, they can highlight both their similarities and eccentricities while portraying a cute concept - double the fun, so to speak. It was also revealed that since they are fans of drinking milk, they decided to add "milk" to their group name.
