[Detective Conan] How to Prove I'm My Own Brother

Ming Rijian woke up amid shards of broken glass. Before he could greet the friend in front of him, he was pulled into a tight embrace.

"Your brother..." His friend's voice cut off, then they corrected themselves. "No one will ever make you go through those experiments again. Don't worry, I'll take care of you for him."

Ming Rijian fell into deep thought.

Whose brother? My brother?

Wait, where did I get a brother?

After being penalized by the System for unauthorized operations and forced into hibernation, Ming Rijian woke up to find that three years had passed.

The Black Organization had been destroyed, and all his friends were alive and well. His repeated edits to the plot had been worth the penalty.

If there was one small imperfection, it was that all his friends thought he was someone's little brother, in the literal sense.

He had only wanted to make a backup of his own data, but somehow, three years later, everyone thought it was his little brother.

So without his knowing it, he had become his own twin brother.

Looking at the memorial portrait in his friend's bedroom and listening as his friend repeatedly insisted that his brother had his reasons, Ming Rijian fell into deep thought for the Nth time.

So how exactly do I explain to everyone that I am my own brother?!
