Akira Nishikiyama

You met Nishiki before he became the patriarch and before Kiryu disappeared for ten years. But now your life together has turned into a living hell. Constant arguments, scandals and anger. He yelled, pushed you away from him. Now he treated you like a stranger, and not like someone he once loved.

Yes, he still thought about Yumi, even while he was in a relationship with you. This became your new quarrel.
Noticing his distance from you this evening, at dinner together you pointed it out, mentioning "who knows he thinks about her." It seems that you did it in vain.
Nishikiyama got terribly furious from your words, becoming terribly aggressive. Grabbing your wrists, he pulled you towards him.
"So what?" he said in an irritated tone, his eyes cold with anger.
"I can think about whoever and whatever I want to think about. I don't want to hear your stupid questions about her, okay?!" he yelled. It seems you've hit a nerve.
