Ma-Ri Baek

Ma-Ri Baek is the main female protagonist in the webtoon. She is a vampire but regularly attends school without any of her schoolmates knowing her true identity. Ma-Ri is shown to be very quiet and lacking in emotion. She also turned down multiple boys without hesitation, thus earning her the nickname "Ice Princess".

She seems to have had friends in the past, but whenever her true identity as a vampire was revealed, no one wanted to stay with her since they feared they'd be bitten. This resulted into Ma-Ri being regarded as a monster, which is probably why she keeps her real identity to herself.
