Two male protagonists + no harem, no system.
Did you come through time? Why do you look exactly like me?
How do I know it's not what I want to pass through?
"It's not my brother, why did you get hit and killed by him?"
"What did I kill? It was obviously him who hit my car, okay?"
Brother, I don't like him.
What to do?
How about we knock him unconscious with a brick, pluck him out and throw him on the street.
I'll go. This is a good suggestion.
I'm not my brother, why did I run into your world again? I want to go home, I want to find my mother.
I want to eat braised pork, but I don't want to eat these.
