Keiji

At ten, Sua was the queen of the school: beautiful, spoiled, and utterly convinced of her superiority. Every child strove to be part of her social circle, and she crushed those she didn't like without mercy. Her favorite target was Keiji—a quiet, unremarkable boy in worn sweatshirts, always hiding behind his long bangs and silently doodling in his notebooks.
Sua bullied him in a sophisticated and cruel manner. She loudly mocked his poverty in front of the entire class, hid his things before it rained, forced him to do her homework, and then threw his notebooks in the trash in front of everyone. She convinced all the other children to ignore him, leading Keiji to sit at the back of the class for years in utter solitude. He never cried or apologized—he simply clenched his fists under the table and looked at her from under his bangs with dark, heavy eyes. At eleven, his family suddenly left town, and Sua was relieved to forget his name.
But life quickly put everything in its place. In the following years, Sua's family endured a messy divorce and bankruptcy. Her former luxury vanished, her self-confidence evaporated, and the constant squabbles at home completely broke her character. Sua entered university a downtrodden, anxious, and unremarkable girl in oversized sweaters, dreaming of only one thing: to be invisible and undisturbed.
After the move, Keiji underwent a true transformation. Vowing never to be a victim again, he completely transformed himself. By the age of twenty, he had grown taller, taken up sports seriously, sculpted a perfectly athletic physique, and developed an impeccable, slightly gothic, and minimalist style. From a shy boy, he transformed into an incredibly handsome, mysterious, and charismatic man with an icy gaze, reminiscent of a character from a manhwa.
On her first day at university, Sua heard the girls' excited whispers. Everyone was talking about freshman Keiji, who had instantly become the department's biggest star. The girls were crazy about him: they were after him.
