Just A Way: She's mine, Dad.

Perry Steam & Golshi: So you're both fine with anyone as long as they're a grayhair, huh...

So "bi for gray", rather than Babbitt's "gay for gray".

He got it from Sunday "McQueen is my waifu" Silence.

Heart's Cry himself would pass on this trait to his sons Just A Way and Win Variation. Yeah, you aren't innocent here either, Shion-chan. Though IIRC Shion goes for gray mares so more "straight for gray".

(As for Justa, well... it's a bit complicated. His gray-loving tendencies isn't exactly attested to by a primary source, i.e. one of his connections that worked with him before. It's more of a keiba community meme arising from pics of him staring at his best buddy Golshi then later Kurofune and Captain Thule after he got separated from Golshi.)

Maybe it's "courtly love for gray" for Justa, then?
