Areum is a leader and fighter, a guide and protector; she is a person who thinks before taking action and is more willing to compromise than jump straight to the battle. She is calm, cool and collected; at least in the eyes of others, because she gives off a feeling of someone friendly and kind. Whenever someone new enters her life, she is sure to guide them in the right direction, to show that whatever they're fearing isn't so bad after all. She enjoys making sure that everyone's doing all right. She's always ready to let people rely on her, but she's a bit more hesitant at relying on others.

While Areum can appear distant or absent-minded, she knows people, to keep it simple. She can look right at someone and almost immediately tell what kind of person they are. There are times where she is right, others where she's been wrong. She doesn't rely on this, but it does help some part of the way when getting to know someone. If you ask for an opinion, she'll give you the truth. Sometimes it can be a bit harsh or brutal, but she speaks her mind. However, as she lives in South Korea, she does know her limits, although might be a bit loose at times.

In the privacy of close friends and family, Areum is honest, outspoken and not afraid to speak her mind. She's bold, brave and athletic, but also a big dork who enjoys being the centre of attention. Still, Areum is a humble and good-natured individual with an odd obsession with Harry Potter and magic. She's a bit of a geek at heart, having a great interest in comic books and video games. She's not fond of choosing sides during an argument, being one of the few times where she prefers sticking in the background and letting the argument solve itself, but steps in if things might get physical. 

Secretly, Areum can be rather insecure. Not about herself, but what she is unable to do. When she gets to do the things she loves, she becomes happy and has a lot of faith in herself to the point of becoming a bit arrogant. Expectations from others and expectations towards herself has led to a lot of hard work, but also a lot of crying herself to sleep at night and long hours awake to perfect her mistakes. She wants to become someone for others to be proud of, and is very insistent of continuing something she's already started. To people meeting her for the first time, there is a friendly smile and a gentle handshake ahead of them. She may seem delicate, but she is indeed a very strong person on the inside.

Kang Areum is a Korean girl who was born on the 15th of August and raised in Incheon, South Korea. She is the daughter of architect Kang Sukwon and his wife Park Jimin, a housewife. Being the middle child, she has two siblings of hers own; an older brother and a younger sister who are two years her senior and three years her junior, respectively. Areum went to a co-ed elementary school and middle school before ending up at an all-girls' high school until graduation. She had always been a very active and friendly child; she was often seen climbing in trees, exploring the park and coming back home with reports on bruises on legs and arms from running and falling somewhere along the way. She had a very close relationship with her family, although the between her and her siblings often resulted in a search for friends outside of the family tree. 
 
When Areum was 14, her parents separated. They moved to the opposite edge of town, wanting to stay away from one another for a while. However, as their own children predicted, it didn't take very long (two-three years) before they were right back in each other's arms, acting like a newly-wed couple and all that stuff. They never got a divorce in the first place, so they just renewed their vows and threw a party for their closest friends and family. Areum always thought her parents were a bit silly, but she loved a good party, so she just went with it and had some cake in the meantime.

Dongwoo is a very sweet and sensitive kind of guy. He can seem a little insecure and even childish, but he is always there to protect those he loves and help the ones in need. He has big eyes that are ready to read and he finds it annoying to be unable to hide what he is thinking about. He is an optimistic and positive guy who gives off the impression of someone kind and friendly, which isn't far from the truth. He can secretly be very possessive and jealous, but doesn't show it very often. 

He is very straight-forward and honest, never really seeing the point in hiding the truth from those around him. He is open-minded and goofy, often having the mentality and energy of a six-year-old boy. When it comes to romantic partners, he is very considerate of his partner and is always there to remind them how amazing and wonderful they truly are. He is loyal and a bit of an idiot, but has a big, kind heart of gold and a smile worth a million.

Dongwoo and Areum are a little similar in terms of their personalities. Both are cheerful, hard-working and sociable with a not-so-secret romantic side to them, but there are also differences. Dongwoo can seem a bit air-headed and not serious at times, which Areum finds adorable and a personal favorite of hers when it comes to him. She finds him funny, considerate and kind, affectionate and a little shy at times. They are quick to open up to one another, wanting to know more and more about each other as time goes by, even it seems like it's standing still when they are alone together. In the beginning, the relationship was a little awkward due to Dongwoo's status as a famous artist and their , but as they grow closer over time, they become more and more like equals and feel like they can trust each other about a lot, even though they haven't really known one another for that long.
