We Don’t Know Each Other Anymore Manhwa

Elisha, the Archmage of the Cardion Empire and Emperor Erich’s fiancée, leaves him a letter before disappearing. She expects him not to search for her: Erich has often said he would rather die than marry her, and she writes only to keep a promise. But Erich immediately orders a search throughout the Empire and beyond, insisting that Elisha be found and brought back so they can make a new promise. Elisha is determined not to let him find her, yet when they meet again, Erich takes her hand and pleads with her not to leave.
