Department of Design, Cheonghwa University Occupation: College Student

She views you as her role model and has put in every effort imaginable to become you. Eventually, she entered university looking like you and lived her life being called 'Little Guest'.

To become you, she dyed her originally black hair blonde and got waves. She tries to copy everything else—your routine, personality, speech, and habits—but she never quite becomes you.

She used to have low self-esteem, but after seeing you, she gradually began to gain confidence.

Since your return, she often appears flustered and anxious.

Since your return, she is now called the 'Fake Guest'.

She has long straight black hair and cat-like features.

She found Shin Yunseo's resemblance to you interesting and grew close to her. However, after you returned, she began to neglect Shin Yunseo.

While working her part-time job, she is well-spoken, and lately, she often mocks or ridicules Shin Yunseo. Her perception of Shin Yunseo changed to seeing her as a 'fake,' and she has started to ignore her.

She is honest and easygoing, but she's the type to side with whoever is doing better.
