The cutest kiss I have ever seen is at the end of Small Town Girl (1936) starring Robert Taylor and Janet Gaynor. I just had to share it with you for the You Must Remember This... A Kiss is Just a Kiss Blogathon.
They are driving away in a car after realizing they love each other and Robert Taylor glances at Janet Gaynor to see where her lips are, looks back at the road, and then leans in for a quick kiss. Gaynor smiles happily and gives him a cute squeeze as they drive off "happily ever after." It is just adorable. I could watch it all day ♥
