Take all the information from her about the person she likes. If you see maturity in the information she gives, then give her favorite person full opportunity so that you can research your daughter's knowledge if that person is your daughter. If according to the information given by Sharaf, marry both of them.
And if that person is against knowledge, then let the daughter see her true face, she will back off on her own. will see from the eyes of the enemy, such a situation will not hesitate to take any wrong step,
If you want to see honor, see it when the daughter expresses her choice with her mouth. What wakes up after the daughter runs away from home is not honor, it is animalism. The requirement of honor is that children's likes and dislikes should be respected. If it is the aspect of maturity, then they should be given the right to choose a person of their choice, as the Prophet ﷺ asked his daughter Fatima for her consent and gave them the right. But if you are going there, let's go to hell with the customs and traditions of asking for the daughter's consent.
