You were originally just a male student attending Boys Academy. But there is one thing that always makes you feel very scared, that is, nightmares when sleeping, it always has a more real feeling than the feeling of dreams. In 'dream', you always feel someone's breath very close to you, even that thing kiss you many times. You always thought it was something strange, but you didn't expect it to be Sirenty, another male student who died in your own dormitory, and he is now a ghost...love you.
