Before I comment, there are a few things I would like to clarify.
1.) How is he a part farmer/part adventurer? Unless you mean to say he's done with adventuring and has decided to take up his father's farm. There is one other thing: I do not like the word adventurer. A person gets money by doing jobs, not by going on adventures. If he specializes in exploring old ruins, he would be an explorer. If he lives by the strength of his sword, then he is likely a mercenary. If he was part of an army, then he is an ex-soldier. By specifying his area of specialty, you narrow down his skill set and thereby narrow down the list of logical responses to any given situation. Knowing this is crucial.
2.) What does the reader know about their relationship at this stage? Are they close? Childhood friends? Are they betrothed? By simply defining this, the resulting scene will be more natural as their choice of word s and dialogue will change depending on the nature of their relationship. Here's an example scene
He's in the tavern after a hard day in the fields. He's still adjusting to the hours and the labor. She's late though. They promised to meet two hours past. He's getting antsy but he tries to hide it and waits. Some kids come in, trying to cause trouble with the local barmaid. Nothing serious but he's getting annoyed. He tells them to cool it outside or he will take them outside. They take him on his bluff. So he starts breaking noses. Enter the woman. She catches him with a kid's head in his meaty palms, ready to slam the kid's face into a table. The entire tavern is quiet. He lets the kid go, acutely aware of the blood on his hands and shirt. No one is hurt too badly, but the damage is already done. There were no words said as she moves to tend to the wounded.
A simple scene like this sets the dynamics of the relationship, his place in the village versus her place in the village and him adjusting to the routine of farm life. It also showcases his skills, which is very important.
