The story originated from a question in a SH story that the author recalled once. The professor had a sexual experience with a girl at the age of 15, and then he said that girl was irrelevant.
Then I suddenly thought, could there really be such a girl, who had such true love and pain, even though she was used as a substitute tool for sexual release, even though Severus was still a young boy like a plant growing in the dark, even though there was no hope or future.

1997, What kind of era it was. So many people survived, their faces stained with tears and blood but still tried to smile. So many people slept forever and could only be looked back from the past by those who survived, and some people could not even be seen in their memories.
In 1997, Harry Potter announced Severus' deeds to the world and learned of his deep love for his mother, but missed a memory fragment, just like the memory owner himself.
In 1997, that memory was finally able to sleep with the passing girl, even though it was so many years late.
