Bomi Hong

In the past, as a student Baekyeon Middle School, she bullied her classmate Hari Ma after she was rejected by her crush, who had a crush on Hari. Eventually, Hari had enough of her acts and slapped her. But before Hari could continue she was stopped by her then boyfriend, Wongi Bae, who dragged her out of the classroom. Bomi watched and smiled gleefully as she was taken away, however, to her surprise, Wongi was whacked by a flying kick from Hari's older brother, Hasung Ma of the Daejeon Alliance. And Hasung confronted Bomi about her actions while her boyfriend lay unconscious. Some time following this incident she broke up with Wongi due to the humiliation she felt being with him after he'd been so embarrassingly beaten by Hari's brother, leading an altercation cut short when his friends, now members of the Alliance, told him to leave her alone. She is led away by them as her ex seethed, unable to act against them due to the risk of being punished by the Alliance.

In the current day, a 1st year student of Baekyeon High School, she first appears with two of her friends bullying Hari Ma in an alley. Bomi gets pissed about Hari's resistant expression but calms down before teasing her about her disabled brother who had her back up until he was beaten into a coma. While leaving the alley, Bomi warns Hari to be cheap, stay out of her sight and jokes about Hari's financial state.

After bullying a classmate at school with her friends Bomi updates her friends on her relationship with Wonjung Jang, boasting of her skill in manipulating him. Upon learning of a guy waiting for her at the school's front gate, she boasts more, assuming that Wonjung had come to her school as a result of he manipulation. However, it was in fact Jigang Kwak of the Emperor's Division who, believing that she liked him, had come to see her. She curses him out before leaving to prevent rumours from spreading, however, due to Jigang's nature, and preference with women, he is only motivated by Bomi's display of repulsiveness. Jigang continues his pursuit, buying out all the coffee milk at her school cafeteria for her. Bomi tries to question Jigang of his motivations, but he only flirts with her, wherein she ends up giving him her number to stop him from visiting her school.

A few days later, still being pursued relentlessly by Jigang, Bomi resorts to calling her crush Wonjung, and they plan to go on a date at Lotte World. While on a call with a friend and picking out clothes for the date she is called by "Wonjung" who turns out o be Jigang, who had beaten Wonjung and his mates, announcing his arrival at her house, telling he that they have to go on a date.
