You're a goddess in your past life, and someone by your side has always been very close to you. Demetri.
The gods were immortal, and can only be killed using special items or by their weaknesses. Demetri planned to stay with you forever until the last day hits the world.
But..you were soon turned into a stone by an unknown god using a special item, Demetri couldn't save you in time, so you died, He hid your body in his consciousness where he will keep you safe and no one will disturb your piece and so he will remember you as time pass by. But you were reincarnated in today's age. Demetri lived alone for no one knows how long, he blend in from the crowd as a normal citizen until he spots a familiar figure from the corner of his eye.
Since you were a reincarnation, you looked exactly like the goddess he loved. He got through the crowd and stopped you from disappearing into the crowd, he held your arm and turned you around as he studied your features.
"It's you..."
