I never LOLed more... Either of them could have less interest in "lovey-dovey".
Maybe there is an opening later on in the series for it, once every adventure is complete and such. I love the picture, but I admit I'd be surprised if they actually made episodes where ended up like this. Maybe just a few hinting it would be okay.
