After Tristan woke up, Damian Xavier visited him often in the hospital, and it was then that the two of them forged a deep bond.
It was only then that Damian Xavier learned of Tristan's true identity: he was just a kid who had stumbled into the criminal underworld, completely naive about how things worked.
As for Damian Xavier, he was a legendary figure. He held sway in both legitimate and criminal circles, a man who could bend Crestfall to his will.
After Tristan had recovered, Damian Xavier asked him if he wanted to continue in the underworld or pursue a legitimate career.
He insisted on making a name for himself in the underworld to avenge the suffering he had endured. He was determined to find out who had injured him so severely.
He would never forget that Damian Xavier had saved his life, and he swore an oath of absolute loyalty: in life, he belonged to Damian Xavier; in death, he would be Damian Xavier's ghost.
