HP: No Regrets

Tom Riddle is the product of a love potion. He cannot understand love, and he must not understand love.

She is light, warmth, kindness, and salvation. She is an angel who has visited the mortal world, Aphrodite's not-so-proud favor, Narcissus's longing for his reflection in the water

But light can fade, water can dry up, and the flame of justice can only visit the mortal world for a little while.

The shimmering, strange illusions form a kaleidoscope. Everything seems like a Möbius strip, its end slowly joining its beginning. No one knows where it all started... Riddle is a coward, but her love isn't.

Theme: He won't regret it, and she can't regret it. Changes can't alter the ending. He is still himself.
