Eien o Ikiru Kimi ni Tsutaetai Koto

Framed for a crime through treachery, a prince fell from a cliff while fleeing and suffered severe injuries. The one who saved him was known as a witch—a being who never ages and cannot die of natural causes. As their hearts touched and connected with one another, they recognized each other as important people and vowed to help one another. However, the two existed on different timelines. Still, the prince and the witch chose to live together, side by side. [Translated from Novelgame]
