Cheon Hae-Won sat cross-legged on Rome's couch with her calculus textbook spread across her lap, highlighting sections with color-coded markers while Mera sprawled beside her eating chips directly from the bag.
"You know you're supposed to review chapters six through eight for the midterm, right?" Cheon tapped her highlighter against the page. "Not just chapter seven."
"Six and eight are boring." Mera crunched loudly. "Seven has the good formulas."
"The midterm covers all three chapters."
"Then I'll study seven twice as hard."
Cheon pinched the bridge of her nose, a gesture she'd started doing more often since Rome entered her life. "That's not how math works."
"Math doesn't work at all unless you pay attention to it." Mera reached over and turned Cheon's textbook sideways, squinting at the equations. "See? Already looks better."
"That's upside down."
"Still better."
