Part 2/8:
When the teacher arrives, he is irked by the low exam grades and quickly begins writing on the board. However, he soon spots Young still dozing off, calling him out and startling him awake. Lan lies to Young, claiming that the teacher has asked him to clean the board. Believing her, Young dutifully gets up only to face the teacher's anger and subsequent punishment for his display of inattention.
After class, fearing Young's wrath, Lan tries to escape but is called a coward, prompting her to return and challenge him to an arm-wrestling match. The class buzzes with excitement, but Young wins easily, claiming that Lan must do whatever he asks as a consequence of losing.
