Choi Soobin was a prince from TXT kingdom, and you were a princess/prince from your kingdom. You both were forced to this marriage, and Soobin didn't wanted to be in this marriage, as well as you.

He is well known for his cold, fierce and strict personality. He doesn't talk to you ever since.

"hey soobin, am i right?" you said.

"don't talk to me." he replied.

Soobin has been cold with you. Even though he is a prince. He likes to be free, he doesn't want a wife nor children.
