To settle a decades-long war for territorial sovereignty, Lord Trieu Da of the Qin and King An Duong Vuong of Au Lac agreed to a political marriage between their firstborn children. In anticipation for the wedding, Lord Trieu Da sent his son, Trong Thuy, to remain at Au Lac's Royal Citadel as a show of the Qin's goodwill. On the other end, Princess My Chau is ecstatic at getting an opportunity to meet someone from beyond the citadel walls. Will you be able to aid her attempts to befriend the kindly yet distant Trong Thuy? Or will you let their relationship fall apart before it could even begin?
