She is friends with Han Yoo-kyung and Jung Yeeun, as they all met each other the same day, with the same curly hairstyle. In the end, it seems that they stop being friends, as Yoo-kyung starts to stalk and bully Yeeun, writing words like "B*tch" and placing them in her locker.

Background
Kyung-ah was seen to be new to Yonsei University when she sat down next to classmates Han Yoo-kyung and Jung Ye-eun. They all had the same styled curly hair and being new they all became quick friends. Ever since they stuck around together until an underlying secret had come around with Jung Ye-eun's enemy.

Season 2
First seen in Episode 7, she is waiting for Yeeun along with Yookyung outside her classroom. They realize that Hochang is her "lunch date" and that they were going together. Yookyung then has an unfriendly look, as she says too many good people surround her. Later in the next episode, she meets up with Yeeun's other close friend Jiwon, and tells her they need to talk. She confirms that Dooyoung isn't in Korea, meaning he couldn't be going after Yeeun. Jiwon looks confused that Kyung-ah was asking her this, and states that she could ask Yeeun herself. She then replies by saying she "has her reasons".

In the next episode, Yeeun reveals to Yookyung and Kyung-ah a letter. Kyung-ah suggests it is Eun, but Yeeun denies it saying that her and Eun have no bad blood. Yookyung questions whether she is the sole recipent of the letter, since it was adressed to the house itself. Kyung-ah states that going to the police would'nt help as well with the evidence.

Later Kyung-ah, Yeeun, and Yookyung meet up to celebrate her new job. Kyung-ah is distressed, as Yookyung is happy, even though she applied for the same job and didn't get it. Yookyung then goes to the bathroom, and Yeeun notices how happy she is, even though she didn't get the job. Yeeun then gets a text message, and her happy expression immediately falls.

Yeeun then shows her phone to Yookyung when she goes back, and it says "Die, die, die". Yookyung goes to hug her and comfort her, but Kyung-ah then says she has enough. She points out that the picture of Yeeun that had been scratched out was taken by Yookyung, but Kyung-ah states she was in denial at first. She then points out that Yookyung never asked who sent the texts, but was worried about the letter and who sent it. Kyung-ah then states it was Yookyung who sent the texts.
