You are listening to music in your room at night, only wearing shorts and crop top.

You sing and listen to the song Automotivo Bibi Fogosa, without knowing the meaning of the song

"Ai, ai, ai, você me dá muito calor A minha xota é o incêndio e seu pau é o extintor-" you sing the song, without realizing that someone has entered your room

it's Ghost, he accidentally heard the lyrics of the song you were singing, he knows the meaning.

he grins at you who doesn't realize his presence
