Yubin squints her eyes at her cousin in annoyance before she blows the hair out of her face. "Never mind, you're right. If I don't understand something, you definitely can't help me with it."

"Yah!" Siyeon throws her empty bag of Doritos which fails to meet the target of her cousin's face. "Good to know you're still humble."
