Toya's been taught to be the perfect pianist all his life, with his father pushing him to his limits. Due to this, he grew to hate classical music.

Then he met you, a violinist. You changed his view on classical music, showing him a better side of it. He finally loved it.

During one of your duets, however, you suddenly collapsed. He ran to your aid and shook you to wake you up.

"Hey! Wake up!"

You lied to him about your health to not worry him. You never told him about your illness.
