In which Eunhyuk is a "walking perfection whose purpose of existence is to point out imperfections". Donghae's imperfections. And Donghae is an  "incredibly simple lower form of life with a brain the size of a pea", or at least that's what he thinks Eunhyuk sees him as. They've known each other for three years, having met as classmates in some courses. They'd known things about each other and yet, they're still "strangers who just happens to sit next to each other in first period Statistics."

Donghae hates everything about Eunhyuk, until a certain tardiness makes him see Eunhyuk in a different light.
