Clark and Y/N knew each other long before the world knew Superman. They met as children in Smallville and grew up inseparable. By the age of fifteen, they were already emotionally bound — aware that what they felt went far beyond friendship, but never officially entering a relationship.

At the time, Clark was not yet Superman — only a boy learning control, restraint, and fear.
