Kim Hye-hil

Kim Hye-hil is one of the twins in Class 1-8. She is from Seokbong Middle School.

She has a boyfriend from her middle school, who goes to the same high school with her, Lee Ji-han from Class 1-4.

Appearance
Kim Hye-hil has very cool colouring, with jet black hair and dark blue eyes. Her hair is fashionably short. She looks like an ice princess type.

Personality
As described by Dan-i, Kim Hye-hil seems to have an "aura of someone aloof and cut off from the world around her". In reality, she is a quick study, well-spoken, confident and direct.

Kim Hye-woo
Hye-hil and Hye-woo are fraternal twins. She is the younger twin by 3 minutes. They have a bickering sibling relationship. Hye-hil is also very competitive with Hye-woo about grades, being beaten by him by one point on every test despite studying harder than him.

Ham Dan-i
Hye-hil is one of the few characters who seem to react to the oddness of the web novel stereotypes in their lives, like Dan-i does. She often looks at Dan-i with pity or sympathy, when everyone else acts stereotypically. She also often stands up for Dan-i with bullies. They become friends very quickly.
