[ID: INVADED] The Lost Deadlock of the Reversing Train

[A short story, written on a whim after catching up on the old series. The original made my stomach hurt from all the angst, so this is a healing happy-ending package.]

Before disappearing, Kohanomachi Koharu's lover left her a text message: "Do you remember where I confessed to you? We'll meet again on the circular train."

In reality, circular trains don't exist.

But I will keep searching for you, like a snake chasing its own tail, sinking its fangs into that slender neck shaped like a tail. I will never stop loving you.
