Someone like that would be a great friend to have for a farmer, so let's take a look at how you can build your friendship through gifts, movies, heart events, and more.

Can you marry Stardew Valley's Demetrius?
Stardew Valley's Sebastian already has a ring on his finger. If that doesn't make the situation easy enough for you, let me be frank: he's married and not interested in straying, so you're better off pursuing a relationship with someone else. You deserve someone who will commit to you 100%, and Demetrius' wife, Stardew Valley's Robin, deserves the same from her husband. However, you can build a solid friendship with him, and you can never have too many friends in a small place like Pelican Town.
