The three of them are born with the ability to see some black things existing in every corner of life. When they accidentally bump into each other's special abilities, two girls and a boy spontaneously come together to get rid of those black things that bring disease and death. It wasn't until they saw "it" with their own eyes that the three of them tasted death for the first time. At a critical moment, a sloppy uncle saved them, but their fate was also reversed...
