Maerineun Uibakjoong

Mary meets a death metal group's vocalist and falls in love with him. Although he is very handsome his personality is not that good. Will those two finally become a couple or will Mary's logic, that it's telling her to not get involved with him, prevail? Note: This was originally a webtoon (Korean webcomic) at Daum. It was adapted into a K-Drama under the same name in November 2010.
