My Journey Through Time and Space

Have you ever heard of time travel?

On March 9, 2050, I received a letter from 25 years ago.

It was a letter I had written to myself.

[Zhihu-style story, time-travel elements, raising a son]

[A no-CP story about falling in love with yourself, but not quite selfcest]

-

The last two stories are just filler and aren't very interesting. Don't bother reading them.

Theme: If only I could return to the past.
