I think the definition of intimate relationship between Kasumi/Sakurako is just different from Moka/Koruri. The two have been so chilled with each other they're pretty much married, plus Kasumi doesn't seem to know or being experienced with any romantic feelings before. Though, Kasumi does rarely show that she cares and can be affectionate towards Sakurako.
Sakurako is obviously smitten but girl never once actually asked Kasumi out, instead she's happy to just live and spend her life with Kasumi.
Also, there's probably a thing about the artist's publisher, they usually try to stretch out the story as much as they can to print out as many manga volumes.
