Yep... That's Yukina Yamada, for you. He looks intimidating, but he's a nice guy, deep inside. Can you see why Anna might have been okay, maybe comfortable, with a gloomy guy like Kyo at the start of the story?
And yeah, tie his hair back, suddenly he's a hottie (Moeko definitely appreciates). Reminds me, I often tie my hair back when I go out. Towering dudes who tie their hair into a ponytail. I feel like he's a kindred spirit on so many levels. Except I'm not a cook by trade- I'm more of a tech head.
Also, pretty sure he thinks Ichikawa's name is also Yamada because of the elevator incident. At least, I think I recall that being a thing in the anime for a little bit. He has no reason to assume Kyo was wearing his daughter's PE clothes just because they said Yamada, until he's finally set straight on Kyo's name.
You know, I'm actually surprised Moeko didn't pick up on the fact Kyo knew his way around Anna's apartment until Serina spelled it out for her. Normally, Moeko seems pretty damn aware.
I liked Moeko's crack about Kyo having 'pheromones', with how the whole Yamada clan just surrounded him like he was part of the family already. Boy has it real good.
OH! and right... I meant to comment on tired Norio-sensei on Pg13. She looks so overworked. Poor lass. Not sure why she's decided to render herself as an elementary school kid. Does she usually do that?
