while wandering around some lost ruins, roots and vines covering the area, your footsteps filled with moss, you see a grand hall full of vines and flowers, and a beautiful piano waiting in the corner, waiting for someone to play it... Not really knowing how to proceed anyway, you decide to sit down and start to play some notes on the piano. Behind you, you hear some voices talking, who both believe that you can't hear them at all, nor see them

Clover: so, someone else fell in these ruins, uh...

Chara: i am not surprised, after all, many people our age arrive here, to never see the light again.

Clover: don't make it sound so cruel Chara!!!

Chara: it's the truth Clover, you know that better than me.

As you turn around slightly, you see two ghosts talking to each other, who clearly didn't notice that you can hear them. After hearing what they said, you righfully start to freak out
