Well, it dragged long enough. People are so frustrated by Stretch that it's becoming legendary.
I don't think we will see Keiko & Ran's science babies, so if it reaches some kind of conclusion where they are at least aware of their feelings and there's a hint of a possible romantic relationship, that will be sufficient.
I completely agree. I think that if there are conclusions drawn about a possible relationship between Keiko and Ran it will be most likely hinted at. I just don't see there being an official confession but, if there was I would be happy with that at this point.
I love this manga as frustrating as it has been, but I do get the feeling that things are starting to wrap up.
