According to what he said,
his father was a very skeptical person.
And yet, he said that he was able to easily prove to his father who he was.
How could a complete stranger someone his father had never even seen before possibly convince him so easily that he had come from the future?
He said that it would be extremely difficult for a time traveler to convince someone from the past that he was from the future, unless that person was a family member or close relative.
He also said that parents were the only people who would have access to everything that could be used to prove who he really was.
So I believe that what he used to prove his identity to his father was the secret song.
Yes.
The same secret song that he later gave to a certain person named Pamela.
He traveled back into the past, went to his family, and told them about the secret song.
His father was then easily convinced.
Because at that time, that particular song had recently had some kind of connection or shared experience with a young Titor.
Only Titor’s mother, Titor’s father, and young Titor knew the secret behind the song.
That is why even his skeptical father was, in a sense, forced to believe him.
After convincing his father, he remained on this worldline and answered various questions on this site.
He eventually left after young Titor knew that he existed, but still did not know who he actually was.
Since he eventually left this worldline, that means there were four people who knew the secret song, including Pamela.
However, young Titor was only three years old at the time.
Because of childhood amnesia, he would not remember what the secret song was or how it was connected to his parents.
So, in reality, there would be only three people who still know the secret.

Right?
When I look at his story, one thing seems certain
I am not him.
However…
I don’t know whether I might be the version of myself from a different worldline.
