Blush on Arrow

Wen Jinglue, an offical of country Jing, is sent to country Qi as an ambassador for the reconciliation between the two countries.

However, the princess of Qi crushes on Jinglue at first sight so the king of Qi offers him to stay in Qi for ten years and marry the princess if it is the peace treaty he wants. To accomplish his mission, Jinglue has no choice but to accept it.

Unfortunately, the king of Jing knows nothing about it and thinks Jinglue has defected after seven years hearing nothing back from him, hence threatenes him to be back at once or else will have his whole family in Jing being executed.

Leaving will break the ten years promise, but staying will have his whole familiy being killed, how should Jinglue make his choice in this dilemma?
