Baek Suzy is one of the main female characters and is the self proclaimed queen bee of Classes 1 & 2. She is the younger sister of Baek Suhyeok who is also the leader of Gyomreong High. She is a trained Jiu-Jitsu fighter who was most probably taught by her brother. She always shows a tough and arrogant side in front of others but is actually a Tsundere mainly towards Kwon Daegun who she secretly has a crush on, as he had saved her on multiple occasions.
At first it is shown that she is mean but in the later parts of the series we see her constantly worrying for Daegun and always trying her best to watch over him.
Nearly all the students except Daegun are quite sure about her liking Daegun but Daegun himself is clueless towards her advances having given her his phone number and not minding the fact that she still calls herself the Queen while he is being called the King of Classes 1 & 2.
Looks and personality
Though it has never been explicitly said throughout the Manhwa, Suzy is considered to be a beautiful young lady. She has a curvy figure, with her biggest assets being her noticeable bust. She has long straight black hair.
In the beginning she is shown to be quite rude and mean, ordering around people just because of her brother's support and backing. But after falling in love with Daegun at first sight she starts deeply caring for him, and making sure that he doesn't get hurt going to the lengths of fake calling her brother once to save him from the second graders. Whenever Daegun is in a fight she always rushes off to see wether he is fine. After being saved by Daegun on multiple occasions her noticeable Tsundere side starts to get seen by her friends and others around her.
When this is pointed out directly to her she gets extremely shy and just starts to deny their suspicion vehementaly. She is also extremely shy around Daegun having trouble looking him in the eye and just admiring him from the sidelines. She also tries finding new excuses to come to his class and spend time with him.
In later chapters like Chapter 93, she does actually make her move but was eventually stopped by Daegun. She later plays it off as a joke when she texted him the next day to hide her embarrassment but received a shallow and simple 'thumbs up' sign from Daegun which made her sad and depressed.
Past and present
Suzy in her childhood
Since her childhood Suzy is shown to be quite cute but extremely bossy. Due to her brother's unconditional love and support she was spoiled, but is kind towards people she actually cares for.
Due to her brother Suzy also had many underlings at her disposal who were always ready to do anything for her at a moment's notice. Even now due to her brother she is easily able to declare herself as the queen bee and never gets in trouble. Also due to her childhood friend Yoo Jiseok who was the previous leader of class 1-5 she was able to maintain control of Class 1 as a whole due to Jiseok's connections with other class leaders.
But from Baek Suhyeok her brother, we learn that she actually grew up in poverty and is an orphan with no one other than her brother. The two of them struggled to the point when they did not even have money for food.
Now with Classes 1 & 2 being under the complete control of Kwon Daegun she now calls herself the queen of classes 1 & 2, thereby associating herself with Daegun as he is called the King of classes 1 & 2. This fact does not bother Daegun much.
In later chapters like Chapter 93, 94 and 95, she directly makes her move on Daegun during the school trip by sitting on his lap and getting very close to him. She was eventually stopped when she tried to kiss him and promptly carried away to her own room.

Fighting prowess

Being trained in Jiu-Jitsu from a young age by her brother Suzy is quite experienced in the martial art having defeated her friend and rival Park Gyuri in the past and then ultimately quitting altogether.
She is shown to be quite strong regardless her physique having put Jiseok in pain after turning his hand in swift movement. She also once kicked Kim Myung Joong who was the previous leader of class 1-2 and inflicted considerable damage on him.
In Chapter 56 she even managed to pin down Daegun even though she was under the influence of alcohol and gave him, a bit of a hard time while he thought of ways to free himself.
Overall Suzy herself is quite strong.
