Although it was not stated directly in this passage, I believe the moment Boaz first saw Ruth he loved her, or at least he liked her. He was definitely favourably disposed to her, to the extent of telling the young men to deliberately drop some wheat for her to glean.
It was the time of wheat harvest, and Ruth asked Naomi to go and glean on one of the fields, which she allowed her to do. As God would have it, she went to Boaz’s field. Boaz was described as a mighty man in wealth, but not just that he was a kinsman to Elimelech, Ruth’s father in-law. Boaz was a godly man, goodly natured to his workers as seen even in the way he greets and treats them – The Lord be with thee.
Also noteworthy was the fact that the good deed Ruth did in following her mother in law down to Bethlehem preceded her. Boaz was aware of this and saw it as a desirable attribute. Leaving father, mother and kindred to join a people you have not known before is similar to what Christ calls us to do when we follow him. It brings to fore the meaning of the phrase, “if you must follow me, you must be willing to leave father, mother, or love me more than family” (paraphrasing mine). Ruth has shown this kind of commitment to her mother in law and the God of Israel whom she decided would now be her own God too.
Ruth was allowed to continue to glean in the field of Boaz right up till the end of the wheat harvest. She indeed found grace and favour in the sight of Boaz and of God.
