⚡ NEW: Id/MiRaGeXiAo - Collection

I can fill a room or just one heart.
Others can have me,
But i can't be shared.
What am i ?

I can be a member of a group, but can never blend in.
What am i ?

I feel your every move, I know your every thought.
I'm with you from birth, and i'll see you rot.
What am i ?

= Loneliness, An individuals, A reflections.
