Nam Hyojin, the "bodyguard". She seems dazed, but is extremely attentive. She appears to be lazy, but is first in her grade. She looks indifferent, but helps out the most. She's there, but then she's not. Chosen to protect the sons of the greatest companies in Korea at the request of her father's good friend, she is sent to a hidden prestige school somewhere in Korea. Will any of the sons be able to figure her out?

"Who are you?"

"... A schoolmate."

"What are you doing?"

"... Talking to you."

"How'd you- where'd she go?"
