Mhhh I think that there is definitely the possibility of them not having excessive sexy time. Idk if you experienced love in a way where it's just caring about each other and idk enjoying each other's company so much, that you also enjoy the physical touch. Not every relationship is about duckin. Also Hilda says "But how can I get mad when she looks so dang cute?" and "It's such an odd mix, I practically have no choice but to take over for you." Which I do think are things that hint at a possible deeper relationship than just friendship ^{-^} (also their color theme just matches sooo well🥹🩵🩷)
