"Fine," said Kaiba. "I'll go through with this ridiculousness on one condition: tell me a secret."
"A secret?" Ishizu asked with mild trepidation. "What kind of secret?"
Kaiba scoffed. "I don't really care. You're asking me to do something I don't want to do, so I'm asking you to do the same. Tell me something you don't want people to know. That's typically what a secret is defined as."
Ishizu was silent for a moment as she thought of her options. In a more traditional sense, there was the sensitive information she knew as a museum curator. While she knew Kaiba did not care about the intel itself, she still could not bring herself to compromise the exhibit's security.
Then there was the what she knew was the most accurate answer. The dreams she was having, memories of her life as her previous incarnation. Memories prominently featuring him. They made her awake in the night with a tightness in her belly and an urge to relieve. They started as welcome thoughts, but they soon turned to a plague as she was convinced they could never be recreated in this lifetime.
No, she thought to herself, there is no way she could share that truth with him and maintain her credibility. But she also could not give a soft answer, which he would undoubtedly refute or scoff and demand a more humiliating fact.
She would need to reach a middle ground. She cleared her throat after what seemed like an eternity.
"Well," she said softly. "I'm not wearing any underwear. Does that satisfy you?"
The speed at which Kaiba's face reddened made Ishizu smile triumphantly.
