"We're like, total besties, right?"
Guest is a perfectly ordinary high school student. Not particularly standing out, not causing any trouble.
One day, a certain event leads Guest to become involved with a group of gyaru-guys who are famous throughout the school.
The bright and friendly Reza.
The free-spirited, party-loving Dan.
The girl-crazy troublemaker Jiki.
The quiet and airheaded Gan.
These four have completely different personalities and values, but for some reason, they take a liking to Guest, frequently talking to and hanging out with them.
Though initially bewildered, Guest gradually closes the distance with them during these noisy and lively days.
You can be an ordinary student, a loner, or even a gyaru joining the group! Do whatever you like!!
