HINO
When Sumire snapped out of her odd daze, she was looking at Toh startled."D--did I--?"
"It's fine beautiful.
Sumire bit her lip. "There is something wrong with me. Every time I drink from you Toh--"
Hino knew what she was struggling to say, after all he just saw it with his own eyes. Indeed, it's too dangerous for Sumire to drink from Mashima. However, the only other alternative she would have for a blood source is him and from what he knows.
Hanyou feedings can get really intimate. He knew it was the reason why Sumire picked Mashima over him the first time. She won't be content just drinking from his hand. If he offered his neck, they would have to get close and that would break the boundary he has been working hard to maintain this entire time. In the end, Mashima is still the better choice. The two were in a relationship before so he knows what boundaries there are. Just now Mashima was being respectful.
