Personally I feel that Shallan and Kaladin work very well. I work in the psychological field and its the similarities that work in a relationship not the differences. I see alot of people stating. Opposites attract, which is true at times, but as time goes its similarities and what is more similar that what kaladin and shallan have? Think of it like this if Shallan talks about her past and her feelings and her life to Adolin im sure he would be a very active listener and would do what he could to be there for her, But can he understand? Does he know such hardship? I feel that Adolin and Shallan are far closer to opposites than Kaladin and Shallan are. When has she disclosed really anything of herself or her life to Adolin? It almost feels more like she is leading him on than anything. Why has there been little depth in their conversations and interactions shy of her just pushing into him to kiss him? I feel like there is just not enough for them to stand on. It may happen and im reading things differently due to personal bias's but I feel Adolin is more the opposite of Kaladin and Shallan instead. Do i think the chasm's was romantic. Very little was. It was more biased on them understanding each other and throughout the entire book its probably the only time where Shallan feels she is the most real with herself and another. The one time she doesn't just hide or lie or try to be something she is not. Its the one time other than maybe with her mentor that she is truly honest about herself and her feelings. That can be a corner stone of romance but that does not mean the experience was romantic. It really does set that table though if that is the path that will be followed. Thats just what I see in it. Feel free to rip it apart and tell me im wrong or have no idea what im talking about
