Song of promise (Ancient Magus Bride Lindel Love Story Fanfic)

It was then when it all began in the coldest part of the world. The world covered with white snow as the cold air pushed harshly against those weak against the harsh winds. A lost traveler stumbled its way into the garden of ice. Seeking nothing but a sanctuary from the cold bitter frost and that was when her heard it. A song. A song of carried out thought the ice gardens and there she was. They met gazes and that was all it took, a promise between the two bonding the two through the age of time. A song and its promise. A promise that could lead to happiness or sadness.
