Perhaps that special room should be opened to her ahead of schedule.
Seeing Theresa fall silent, Otto simply ended the conversation.
"My lovely Theresa, I do not wish to see your face clouded by gloom. Hawaii is a nice place. Perhaps you should find time to take a vacation there."
Having offered his suggestion, Otto left the room.
Yet instead of returning to his laboratory immediately, he went to that secret room.
Watching the holographic projection of a young boy and girl playing together, he unconsciously raised his hand... wanting to touch the woman he could never touch again.
At that moment, his eyes were filled with that beautiful figure.
Every smile and frown seemed like yesterday.
Otto fell silent.
All his close friends had become sacrifices to the truth, and all his loyal subordinates were merely chess pieces. Even with Void Archive, which was practically one with him, he remained vigilant at all times.
He had been lonely for centuries. He still remembered the happy days spent playing beneath that blue sky and those white clouds, on this very patch of grass.
He could not forget the figure who had left so resolutely.
Nor could he forget the heartbreak of hearing her loudly announce in the Chamber of Judgment that she had fallen in love with someone else.
Love or pain.
Both had become the faith that allowed him to persevere.
The kind-hearted Otto was dead.
Otto had always said so, and always believed so. Yet he still possessed the emotions of an ordinary person.
When he personally gave the order to eliminate close friends, his heart still ached.
When facing Theresa, his heart still softened.
"Kallen... I miss you."
Otto murmured unconsciously.
A person could live for a long time, but their mind might not.
He was tired.
