They're making their debut with the song "No Way", which was composed by Jong Tae Eun in collaboration with 17Holic. It definitely has a different style and sound than we're used to from Chrome Entertainment, so it's worth checking out!
If you're wondering about their name, it's said that rather than referring to the bob hairstyle, the name is supposed to indicate the change or transformation within a woman that happens when she cuts her hair short. In addition to a change in experience, her heart and mentality can also experience a change, and this is what their name is supposed to refer to.
So check out the girls in their MV above!
