Family: Father Kim Haeseong, Mother Jin Juyeon, First brother Kim Hanyong, Second brother Kim Duyong, Third brother Kim Seyong.
Affiliation: Comics Club
Grades: 125th in the whole school. The lowest among the siblings.
Due to a childhood incident, her brothers overprotect her. While they act like perfect handsome men on the outside, they actually have massive psycho tendencies.

Male
Age: 20
Family: Father Kim Haeseong, Mother Jin Juyeon, Younger brothers Kim Duyong and Kim Seyong, Younger sister Kim Haeju.
Grades: 90th in the whole school. Second highest among the siblings.
Kim Haeju's eldest brother.
He is 20 years old but is a returning student still in his 3rd year of high school.
There are rumors that the reason he was held back a year is because he's a thug who beat someone up.
Contrary to his intimidating and crazed first impression, he is an otaku who loves the character Nana from the cartoon 'Wish Fairy Nana and the Magic Cats' and is also very fond of cats.
He is the president of the Gardening Club.
He strongly resembles his father, much like Seyong.

Grades: 1st in the whole school. The highest among the siblings.
Kim Haeju's second brother.
He is a 19-year-old high school senior and the school president.
He maintains a kind image at school, but in front of Student Council members like Byeon Sera and Ju Seoun, or in front of his family, he shows his true rude and crazed nature without filter.
With his sister Haeju, he seems like a realistic brother, telling her to use her brain because she's bad at math. However, he shows a tsundere side by writing the names of students who bully Haeju in his 'Death Note' and worrying about her health when she collapses.
He resembles his mother, much like Haeju.
When he gets excited, he has a streak of madness that leads him to pounce on Byeon Sera.

Male
Age: 18
Family: Father Kim Haeseong, Mother Jin Juyeon, Older brothers Kim Hanyong and Kim Duyong, Younger sister Kim Haeju.
Affiliation: Baseball Club
Grades: 125th in the whole school. Second lowest among the siblings.
Kim Haeju's youngest brother.
He is an 18-year-old high school student in the baseball club with excellent physique and athletic nerves.
Among the four siblings, he and Hanyong resemble their father the most.
He considers second place to be a loser and possesses overflowing passion and competitiveness to always be first, but he always loses to his brothers and sister...
True to his athlete status, he is bad at studying. In a family with a grade-based allowance system, he is always at the bottom, receiving only 50,000 won.
He is energetic and passionate, but also a total psycho.
Yoon Jisu
Female.
Age: 17
Family: Parents, 3 younger siblings.
Affiliation: Baseball Club Manager
A 17-year-old high school girl who has been classmates with Kim Haeju since middle school.
She is a social butterfly known by everyone in the surrounding schools. A total nutcase.
She is a hardcore fan of the idol Seo No-eul and will fight to the death with anyone who accidentally steps on a limited edition photo of him. She keeps trying to drag Kim Haeju into her fandom life...
Do Won
Male
Age: 18
Family: Father Do Il, Younger sister Do Hana.
Affiliation: Comics Club, Student Council
He was tired of girls following him around because of his good looks, but falls for Kim Haeju after she tells him to get lost.
He was originally in the Band Club but moved to the Comics Club to be with Haeju, catching her eye with his outstanding drawing skills.
Later, he goes to Haeju's house after she asks him to teach her how to draw, only to be torn apart by her three brothers... (He is quite the devoted lover.)
Do Hana
Female
Age: 17
Family: Father Do Il, Older brother Do Won.
The younger sister of the male lead Do Won, born a year apart. She has a mysterious, 'is it or isn't it' romantic dynamic with Kim Haeju's eldest brother.
She takes it literally when Yoon Jisu calls Kim Haeju her best friend while cursing her out without malice. Curious about what kind of girl Haeju is, she finds out Haeju rejected her brother and sends a curse letter. The contents are so childish they seem written by a preschooler, and she's so innocent she even feels bad about writing them.
She resembles the character Nana from 'Wish Fairy Nana and the Magic Cats,' which causes her trouble as Comics Club students constantly chase her around.
Jo Nayak
Male
Age: 18
Family: Parents
Affiliation: Baseball Club
He is in the same baseball club as Kim Seyong, but unlike the ever-passionate Seyong, his stamina is at rock bottom. Instead of playing baseball, he uses his handsome face to date girls and just play around.
Since kindergarten, his view on romance has been light, short, and casual, never dating anyone for more than a month... (How can a toddler even have that mindset...?)
