Till We Meet Again (1950)

Saburo is a student, who first sees Keiko in a bomb shelter during the American air raids on Tokyo in the Second World War. As a close one hits, he shelters her and she lays a gloved hand on his. He sees her again at a railroad crossing, then meets her at a publisher, where he follows her. They talk, and after other meetings, touch hands. Then, in the cold, he places her bare hand inside his jacket. She's an illustrator of war posters, but he convinces her to paint his portrait, and when he leaves, he comes back to see her in the window. Crowding into a corner when a stray bomb lands, he gives her a kiss and tells her he has been called up.
