Superman #67

In "The Secrets of Superman!", Superman prepares a time capsule for future generations, including a personal message revealing his secret identity as Clark Kent. When the recording goes missing and he begins suffering from memory lapses after a recent explosion, he becomes determined to recover it before the capsule is sealed.

In "Mrs. Superman!", Lois Lane hatches a clever plan to marry Superman by orchestrating a fake engagement between Clark Kent and one of her friends—hoping the ruse will make the Man of Steel realize his feelings. But when Superman catches wind of the scheme, he sets his own clever counterplan in motion, turning the tables in a way that tests both love and identity.
