This is definitely not an accident

Between the Pak and Han families, there had always been a feud. In order to end it, Han Gwanseon proposed a marriage contract to Pak Yeonmi, but she ran away with her lover. Instead of breaking the contract, Gwanseon decided not to waste time and took her brother, Pak Jiwon, who was unaware of what was happening and would have been against it, as he hated Gwanseon. In reality, Gwanseon’s goal from the very beginning was not to marry Yeonmi, but to get his hands on Jiwon.
