LEWIS HAD nothing to say to his other self called 'Lu.'
This person serves the wrong master, after all.
In short, he didn't like this version of himself.
"Why did you choose to serve Princess Neoma in this world?"
"Only kind. Royal. Strongest."
Yes, Lewis talked like that on purpose because he didn't want to talk to Lu.
But Lu seemed like he didn't care because he opened his mouth again.
"I served Prince Nero because I was gifted to him as a child," Lu said even though this person knew Lewis had no interest in anything he was saying. "I feel a strong sense of duty to protect Prince Nero. But that doesn't seem to be the case for you— it seems like you care about Princess Neoma on a personal level."
"None. Business."
"Yes, I know it's none of my business, but I'm curious. It seems like the world where you've come from is far more interesting than this world."
"Life. Yours suck. Wrong master."
