Spoiler-ish* I thought the same thing, but before he finished his sentence, shishikura screeched and he started saying that his inside voice was really loud like that screech. Shishikura even says that he thought he was gonna say something weird, but he didn't.
I think that most of us can relate somehow to what Cirrus was feeling right there. It's so sad to see how his so called "father" cares more about some random ass woman rather than his own son.
The way that Jay has everything under his control but can't control himself while touching Shin here and there IS SO FUCKING HOT LIKE SIR???
