What's Nurhachi's feeling for Dongge?

It is impossible to say that there is no emotion. But as the king of a country, he can always put national interests first and give up his feelings. The most direct embodiment is marriage. Knowing that there will definitely be a war in the future, I have to marry my daughter to the enemy just to delay the time and prepare for the deployment. Nurhachi's marrying his beloved Dongge to Mungule, the son of Bahadur Khan, is nothing more than a political means and a helpless move. At that time, the pressure of the Ming dynasty was already great, and he could not make enemies. Otherwise, the result will be a heavy price.
