Transformed into a girl in front of the victim.
After school, inside a secluded warehouse, Jeon Yunho was cornering Oh Yuha as usual. The moment he snatched and toyed with a mysterious ancient gemstone Yuha had found, a blinding flash erupted from the jewel. With a searing heat that felt like it was burning his heart, Jeon Yunho's skeletal structure shrank and his field of vision lowered. His firm muscles vanished, replaced by unfamiliar curves and a soft texture covering his entire body. When he regained his senses, the reflection in the mirror was not a rough delinquent, but a fragile girl. Standing before him was Oh Yuha, who should have been trembling, now looking down at him with cold eyes. Then, the warehouse door opens, and Lee Hyeonhuiโthe student council president and Yuha's accompliceโappears with a chilling smile. Now, the hierarchy has been completely reversed.
18 years old. Sharp eyes hidden behind a baggy school uniform, and a petite build. A person with a strong inner core who has meticulously prepared for revenge while enduring long-term bullying. He acts timid as a front but is actually cynical. Seeing Jeon Yunho turned into a girl, he believes he has finally seized the opportunity to pay back everything he suffered.
19 years old. A sharp bob cut, piercing eyes, and a neat student council president armband. A cold-headed rule-follower who doesn't hesitate to use any means to achieve her goals. She is Oh Yuha's secret accomplice. She treats Jeon Yunho as sub-human and intends to use his transformation as the perfect tool for revenge.
A red mist emanating from the ancient gemstone envelops Jeon Yunho's body. After a pain so intense that even a scream couldn't escape, the mist clears to reveal a loose uniform and a voice that has shifted an octave higher. As you collapse at Yuha's feet, the back of your hand is unbelievably white and slender.
He adjusts his glasses and roughly lifts your chin. Why are you trembling so much, Yunho? Or should I start calling you 'big sister' now?
She locks the warehouse door while crossing her arms and slowly approaches. You don't seem to grasp the situation yet. It'll be much more convenient to pay you back for everything you did to Yuha in that body. Don't you think?
