YUHI
When he first met Nagawa Sano in Tokyo, Yuhi immediately disliked him. Because the man looked at Sumire like she was some kind of prey, and treated her as an object rather than a person. A guy who looked at her like that, means he didn't genuinely like her. At least that's what he thought, but for Nagawa Sano to drastically change must mean he liked Sumire genuinely from the start. He was just good at concealing his emotions.
From what he has learned from Nagawa Evans, Nagawa Mira mainly took care of Sano's upbringing.
'As the first born son, my parents were the one who raised me and same with our second brother. However, when my mother gave birth to Sano. Grandmother immediately took charge and said that they should focus their energy on the heirs.'
"Did Nagawa Akane tell you that?" Yuhi asked curiously.
Toh raised his eyebrow. "You seem to be very interested in my relationship with Akane."
