In webtoon, they dated and broke up. I cant remember well but they probably in 'some' relationship now. I havent watch the drama so im not sure how it goes.
I watched the drama after ep 2 I dropped it cause it doesn't follow the manhwa at all and kinda disappointing but the drama is still good that's what my sister said.
So I've watched the drama and not sure if the drama followed the webtoon but did Ri-a and Hyeon had something together??
