Identity V + Sky: Children of the Light: Orpheus and the Child of Light

I've lost my memory. That's the only thing I know for certain, until a letter arrives and I go to the address written on it.

In the forest, I meet a strange child. I think I'm hallucinating, until they get into my car. They have a letter too.

Well, maybe I do have a companion after all. Right?

Notes on the setting:

① I've been a player for eighteen years, though I took a break for a while afterward. The story that follows differs from NetEase's version, and the setting is different too. Every character who appears is one of Orpheus's personalities.

② There are more or less two points of view. Orpheus is the protagonist, and the Child of Light here has no gender or nickname, so they're simply called the Child of Light.

③ No pairings and no romantic tension. There is out-of-character writing. If it makes you uncomfortable or isn't to your taste, please read something else.

Theme: What you see with your own eyes is not necessarily the truth.
