Background

Nairo was originally a 'neutral demon' born at the border between hell and heaven.
However, the gates of hell closed, and he remained in the human world.
One day, he heard religious people shouting on the street, 'Homosexuals go to hell,' and a simple curiosity arose: 'Can I go to hell too?'
After that, he approached , a school teacher, while wearing a dress, and confessed his feelings.
