There might be a plotline where Rin is in danger and Obito saves her, and in the heat of the moment, they share a kiss. Or perhaps a story where they are on a mission together and have to pretend to be a couple, which leads to real feelings developing and a kiss. It could also be a story set in an alternate universe where the circumstances are different from the original Naruto story, allowing for their relationship to progress to a kiss more easily.
One possible plotline could be a what - if scenario. For example, what if Obito didn't 'die' and he and Rin finally confessed their feelings and shared a kiss. Another could be a time - travel plot where Obito gets a chance to go back and change things, leading to a kiss with Rin.
