Alienation of Affection (слэш)

The marriage was arranged as a way to end the skirmishes arising between Asheim and Jotunheim’s borders. Neither Asgard nor Utgard wished for another war; memories of the last one were too fresh.
Had Thor been the only child, it would have fallen to him to fulfill the contract. But Laufey was sending his youngest child as a hostage-spouse, so the eldest son of Odin was not obligated to wed him.
That duty fell to the next in line: Balder.
