Summary:
From Infinity Studios:
A young man finds and returns a lost wallet and cell phone to a beautiful young lady, thus begins the destined relationship between two strangers. Sound typical? Well then, how about making the young lady the young man’s future homeroom teacher, and give them both a twisted sense of right and wrong. And just for kicks,
let’s have the young man help himself to a self proclaimed reward from the lost wallet before returning it…but of course, this scenario wouldn’t be complete unless the young lady was very unforgiving when it came to teaching one of her students a lesson on morals.

Characters


Jin-Ho Myung
He is in the final (senior) year of High School and finds himself a student in Hae-Young's class, seemingly caring little for schoolwork. He has been known to go to the nurse’s office to sleep, watch erotic movies in school, and complete mathematics tests (generally unsuccessfully) using pure guesswork. In middle school, it appears he was something of a delinquent who got into fights, and he has become quite skilled in them. This has been a source of concern to his family, at the very least for his aunt. However, he can also become focused if something interests him, like film, which causes him to be the co-founder and eventually the president of the Film Studies Club.

He lives with his Aunt and father and there are suggestions in the story that he is estranged or separated from his mother, a possible cause for some of his behavior[2].

His sometimes rather cavalier attitude leads him into a number of compromising situations with his teacher. These instances have led Jin-Ho to fall in love with her.



Hae-Young Nah
A young, beautiful woman in her mid-20's, who teaches mathematics and also acts as the homeroom teacher for class 3-2. She lives with her sister and niece in an apartment block quite close to Jin-Ho's. Her father’s unexpected departure from her life when she was young has had a huge impact on her. Even though she is extremely attractive and was apparently popular throughout her school life, she has become very guarded around men, feeling unable to trust or form relationships with them. Consequently she is still a virgin and even has her first kiss during the course of the story [3]. She also seems to be following her mother's career path, who was also a teacher and became the district superintendent before retirement. Despite Hae-Young being strict and meticulous, she has found herself in increasingly compromising and desperate situations with her student, Jin-Ho. Much to her own initial displeasure and discomfort, she finds herself beginning to have romantic feelings for him.


Caroline
She is a Eurasian (half Korean/half British) woman, recently arrived in Korea. She has lived in the United States for a while, learning the French martial art of savate. She has come to Korea because she is curious about her father's homeland and her siblings, who turn out to be Hae-Young and Hae-Jung. When she first arrives she lives temporarily motel while her father arranges for her to stay with her half-sisters for about a month. She has been employed as a language teacher and an assistant homeroom teacher under Hae-Young.

Her first encounter with Jin-Ho, like her half-sister's, is not entirely without its troubles, ending in a fight and injury for her. Her opinion of Jin-ho changes however when he escorts her back to her motel room and shows concern for her well-being. As she has no full siblings she appears to harbour a strong desire for a warm relationship with her half-sisters, though this is complicated somewhat by their rather cold and distant relationship with their father. She expresses great romantic interest in Jin-Ho and has challenged Hae-Young Nah to see who can first win his heart.


Young-Gi Cha
He is also a senior, who is Jin-Ho's friend and classmate. They have been in placed together in the same class for the previous five years. Like his friend, he is skilled at fighting, but prefers to avoid confrontation where possible. It has been implied that he likes Ji-Soo; he is very protective of her and careful of how she perceives him.


Ji-Soo Ha
She is the senior class president as well as now being the president of the student council. She is hardworking, studious, performs well and is also popular. She appears to have liked Jin-Ho ever since the freshmen year of high school, when he helped her make origami flowers. He does not feel the same way towards her, though at one point he does suddenly notice that she is attractive.


Ami Eun
She is a senior and friend of Ji-Soo. She is shy and quiet at school, where she often reads yaoi manhwa. She is one of the first to find out about Hae-Young and Jin-Ho complicated out-of-school relationship. When Jin-Ho learns that she is the one who told Ji-Soo about his situation with Hae-Young, he attempts to confront her. During this face-off she threatens to publicly reveal the relationships, which would be likely get Jin-Ho suspended and, worse for Jin-ho, ruin Hae-Young’s career. She even forces Jin-ho to kneel infront of her.It transpires that this was an empty threat, since Ami herself is also in love with Hae-Young, she even goes as far as trying to force herself on Hae-Young.


Jae-Kyung Park
She is a college freshman and a friend of Jin-Ho's. She was the co-founder and former president of the film studies club as well as the former president of the student council. Even though she flirts with him, Jin-Ho feels comfortable enough with her to confide his girl problems to her. There are also hints that Jin-Ho may have had rather deeper feelings for her [4] while she was in high school. It seems that Jin-Ho has been rather more distant with girls since she left [5].

Hae-Jung
She is Hae-Young's older full sister and roommate. She is also, therefore, Caroline's half-sister. Like Hae-Young, she has not forgiven her father for abandoning them as children. She is the mother of a four year old girl, Mina Choi.

Ji-Sun Myung
She is Jin-Ho's screen writer aunt who lives with him and his father. She often talks to and looks out for her nephew and is not afraid of hitting him when she thinks he has gone out of line. She also acts to diffuse tension between Jin-Ho and his rather authoritarian and distant father.

Sung-Chul Nah
He is a documentary film maker, as well as being the father of Hae-Young and Hae-Jung. He left his family to go to United Kingdom, though there is some question as to whether he or his first wife initiated the separation. In the UK he fathered his third daughter, Carrie, with a British woman named Grace Pendleton [6]. Even though his eldest daughters will not forgive his leaving them, he has asked them not to take out their frustrations on their half-sister Carrie.
