Honeymoon to Nowhere — Akimitsu Takagi

Etsuko has fallen in love with the shy young university lecturer who clumsily courts her. But her family objects to his past: his father was a war criminal; his deceased younger brother, a murderer. When Etsuko lies to force the marriage through, she thinks their troubles are over, but on their wedding night, the groom leaves in response to an urgent phone call. In the morning, he is still missing.
