I hope he doesn't fall in love or marry Rong Rong. He should totally marry someone that doesn't have that much backing like Rong Rong. He should totally build his own clan or rebuilt the Hyuga or Otsutsuki Clan here. If he marry Rong Rong he will bind himself to her clan.
no he will not be tied by rongrong clan, because I have set for him to become a king of the kingdom he creates from the former territory of barak kingdom plus spirit hall territory and only those of his desentdant who awaken byakugan can become the king. and royal family will be conquered by his descendants with byakugan eyes.
