Miss Time

Lee Gaon is a successful personal trainer who has always had a personal rivalry with Jiho, a famous romance novelist known for his badmouthing attitude. Gaon went to her frenemy Sera's wedding ceremony and somehow ended up helping her escape(?). And the unlucky groom? It was Jiho, the man who had always insulted her over the years. As they argued, they finally realized they were from the same high school class, and that he wished things could've turned out differently... That was when the two were suddenly transported twelve years into the past... "That soft writer was the badass delinquent in high school?! And he liked me as well?!" How will their incompatible personalities turn out, when given a second chance for romance? (Source: Bomtoon, translated)
