Gu Zhinian and Xia Wanning have been childhood friends for as long as they can remember, yet they’re the most mismatched pair at school: he’s a top student who can solve any problem, while she’s a struggling student who can’t even remember her formulas. Every day, they bicker and spar in the classroom, their squabbling turning them into the sort of rivals who can’t help but enjoy each other’s company. Before long, their unspoken feelings begin to blossom. When those feelings finally come to light, they clasp hands and resolve to work hard until they can both enter the same university.
