As soon as I woke up, I knew I had entered a novel world belonging to a time-traveling girl group favorite! The heroine has her own heroine halo! But... So what? So what if I'm a supporting actress? I have awakened to the plot, then I will get back my own halo bit by bit! The heroine and the supporting character, if you don't give it a try, how do you know you're not good at it?
Intention: Don't give up easily
