Yuna Lim

Yuna Lim (임유나, Lim Yuna) is one of the main characters of Odd Girl Out. She appears to be cold-hearted and rude but is actually a kind and caring friend towards Mirae Seo, Seonji Lim, and especially Nari Oh.

Background
Yuna comes from a very wealthy family as seen in many cases and is childhood friends with Nari. However due to a misunderstanding in middle school, the two temporarily ended their friendship before reuniting three years later at high school.

Appearance
Yuna is known to be very beautiful, to the extent where the students have said it is "illegal to be that pretty", and has been idolized by many, notably Bin. She has dark blonde, approximately waist-length, hair which she usually keeps down, and a mole under her right eye. She has grown notably taller during the period she was stuck in her room after she was heavily injured in a car accident. Throughout the Webtoon she is often seen wearing her school uniform, though she has been seen wearing other clothes (mainly branded) when outside of school.

Personality
Yuna appears to be cold and arrogant, not seeming to pay attention to her surroundings. After she was involved in a car accident with her mother her personality changed drastically. She started having trust issues because of her abusive teacher and her friends who looked disgusted and shocked after seeing the injuries she have gotten from the accident. Nari was the only one who stood by her side which is why Yuna is nice only to her. But in the end of season 1 she seemed to become much softer and nicer.

Nari Oh
Nari was friends with Yuna since she was a child, though their relationship consisted mostly of Yuna bossing around the clueless Nari. After Yuna's accident, Nari was the only person to stick by her, which was the reason why Yuna is only kind to her. Nari is now her closest friend.

Mirae Seo
Mirae - going by Se-Ha - and Yuna first met at Rainbow Academy, where they took acting classes. Yuna was also in Se-Ha's school, and the two had a rivalry. After Se-Ha's career failed, she waited in the academy disguised with a hoodie and saw Yuna enter. They had an argument, and Se-Ha challenged Yuna to see if she had any friends. Yuna called Nari, and eventually gave Se-Ha her number. When Se-Ha hit rock bottom, the only person she talked to was Yuna, though, they mostly threw insults at each other; despite this, when Se-Ha found out what high school Yuna was going to, she decided she didn't want to leave Yuna, and went to the same high school as her while also changing her name to Mirae. They kept their friendship secret.

Seonji Lim
Yuna and Seonji had a distant relationship at the beginning due to them being opposites. Later, Seonji attempted to get closer to Yuna, and they did during a sleepover because of Seonji taking care of a bug that landed on Yuna. Later on, it is revealed they met every Wednesday, where they talked and fed the janitor's dog together. They also worked together to collect stickers to make Nari's wish come true.
