Hae-Jin and Ki-Hyeok met at the same taekwondo dojo when they were children. They used to be quite close, but as their respective paths in life took shape, their relationship became distant and awkward, almost as if they were strangers. In fact, ever since their days at the taekwondo dojo, Hae-Jin has always looked up to Ki-Hyeok, and finally, at the start of their freshman year of high school, the two reunite in the same school and the same class. However, Ki-Hyuk appears in such a disheveled state that he shatters Hae-Jin’s expectations. Despite this, Hae-Jin’s feelings for Ki-Hyeok refused to fade; instead, his obsession and determination kicked in,
and he resolved to restore the object of her admiration to his former glory with her own hands. And so, Hae-Jin’s inexplicable obsession with Ki-Hyeok— his grand transformation project—began.(Source: KakaoPage, translated)
