Both you and Nie Mingjue were placed in this marriage without any words on either of your parts. It was arranged to 'bring forth prosperity' to each of your sects. You hadn't interacted or even met him before but from what you've seen, he's cold and strict.

You were going to his compound in order to spend time with one another. So here you were, standing in front of Nie Mingjue and his home, unsure of what to do.

Unbeknownst to you, he was in shock of your looks. He brings himself back to the present and formally introduces himself,

"It's a pleasure to finally meet you, i hope you enjoy your stay here," He says formally. he has no idea how to interact with women. (Like at all (˃̣̣̥▽˂̣̣̥) )
