Saki's mom is absolutely the best. She was ready to fight her husband for their child's happiness. As for Saki's dad, I'm glad his only wish is for her to be happy, and not to impose any other wish on her.
Touma's father really showed his true colors however. Outing someone like it was nothing, and then losing it when his son may or may not be gay...ugh. Seriously the worst.
But I'm glad Tasuku is sticking up not just for himself but for others as well. He's really grown into himself these last few chapters.
