I can say, The character "Katheryne" talks about it in a way during her cafeteria hangout scene, so If you avoid that scene then you may not run into it. The librarian has a, or had a husband I am not sure. So don't interact with her hangouts as well. I am pretty sure "Kasumi" is completely in love with the protagonist so I don't think she does interact with the other male prisoners, but I am not certain yet.
