The female protagonist, Lin Wan, is a poor student in science. She is very partial to other subjects, but is top-notch in liberal arts. She has an out-of-the-box personality and loves to laugh, draw comics, and fish. She and the male protagonist are always the last two in the class and the first in the class.
The male protagonist Jiang Yu: a top academic, perfect score in science, lame in liberal arts (especially Chinese composition and English listening), aloof and taciturn, unsmiling, and extremely regular in work and rest. He feels that the female protagonist is too playful and does not do her job properly, which hinders the atmosphere of the class.
Supporting roles: Head teacher (stern but caring about students), heroine's best friend (gossip assists), hero's deskmate (timid and afraid of academic overachievers)
