The water is filling up the tub. He pulls her up, making her sit in front of him. She doesn't meet his eyes. So, the real reason must have been this. "You think that I won't find you sexy after seeing it?"
He sees her biting her lower lip, looking sideways. Kiyohira realizes that she can't believe him no matter what.
If he had followed his guts and confronted Chisa back then, this could have been prevented. This woman, who would take her clothes off and try to seduce him without a second thought, wouldn't be like this. He's at fault for not being able of saving her and their child on that day.
Kiyohira cannot let her become imprisoned inside this cage. He has to make her realize. He lifts her chin and says, "Want to test my feelings?"
Something changes in her eyes. She doesn't want to test his feelings. What if he fails the test?
