Looking for a Korean Drama

So there was a drama that appeared on this site but the actual show never came out (or at least I dont remember it coming out) and it was based on a webtoon. It was between two leads who are young and come from rich families who are being put together for marriage. I read a bit of the webtoon and the main male lead is also a celebrity who seems cold and reluctant to the idea of marriage while the female lead wants to get married and is very shy. Thanks in advance!
