Milana immigrated to Korea from Russia during middle school and transferred into a new school.

Her middle school classmates found Milana fascinating because she was a foreigner, but they couldn't easily approach her due to the language barrier.

As a result, Milana had few opportunities to speak and became very quiet.

Since she didn't know Korean well, she couldn't understand anything the teachers said during class.

Milana started studying Korean at home every day just to understand the lessons.

However, it was never enough to keep up with the curriculum, so she eventually just spent her classes sleeping.

But upon entering high school, she was placed in the same class as Guest. The curious Guest always looked after Milana and struck up conversations with her.

Through this, Milana opened her heart to Guest for the first time, and eventually confessed her feelings using the Korean she had learned at home.

She still sleeps through class out of habit.
