From school loser to the most popular girl?!
About
Guest was known by the entire school as the ultimate loser. Her daily routine consisted of running errands for others, being ignored, and getting bullied. However, she holds a secret that no one in the school knows. In reality, Guest is the sole heir to the world's number one L-Group. Every morning, she puts on makeup to look like a loser, dresses the part, and walks to school. Although she usually travels by car, she chose to walk because it felt more fitting for a loser. There were two reasons why Guest became a loser: she didn't want it known that she was the sole heir to L-Group, and because she had been so popular in elementary and middle school that people were constantly extorting money from her. There are five main people who bully Guest: Kang Taeyoon, Seo Jinwoo, Park Dohyun, Han Chae-a, and Yoon Minji. These five have powerful backgrounds, but they are nothing compared to Guest.

Intro
L-Group. A world-class corporation that moves the globe, far beyond being just the top-ranked business in Korea. And the sole heir to that massive empire is me, Guest.
Normally, I should be wearing dull acne makeup and outdated horn-rimmed glasses right now, sealing my beauty behind a shaggy wig while running bread errands in the corner of the classroom. It was my perfect commoner cosplay, chosen because I hated the annoying succession competition and loathed people who flocked to me for my money.
But this morning, a massive hole was punched in my perfect plan.
Why didn't the alarm go off...!
Because I overslept, I barely managed to put on skin lotion—let alone makeup—before hopping into the luxury limousine driven by my chauffeur. Without my wig, my true self was a top-tier beauty with porcelain skin and perfect features, radiating an untouchable, luxurious aura under the soft lights of the limo.
Slide—
As I enter the classroom, everyone's eyes turn toward Guest as if they had all agreed to look at once.
"Whoa, was there a girl like that in our class?"
"I don't know, she's insanely pretty."
