tbh in my headcanon conception of them zutara is not super pda-heavy. they like being near to each other, they can read each other’s expressions really well, they gravitate toward one another almost without thought (even before they get together), and they’re very much the “sit on the same side of the booth” couple and pretty much always know where each other is in a room at a given time.

but those intimate gestures—holding hands, kissing, gently cupping each other’s faces, comforting embraces—are something they largely like to keep private, something just for them.
