Could Kenji and Rin be friends?

Let's say these two are on the roof and there is no one else, what would a conversation between them be like? Would Rin listen to Kenji? Would he ignore him? Could they become friends? (If anyone knows of any fanfic about these 2 I would love it because I can't find)
