because it’s cute as hell and Nicole Beharie’s smile/laugh gives me butterflies, but also because have you seen how he looks when she does it? He rarely looks annoyed, if anything he looks pleased even (especially?) when it’s at his own expense, and if you try to tell me he didn’t to that exaggerated straw-sucking thing on purpose to make her laugh then I will thank you kindly to see yourself out because he 100% did and I will not sit here and listen to lies.
It adds such a great extra layer to their relationship because they very easily could have just had this bickering-like-a-married-couple/”you get on my nerves” deal going and that still would have worked - does work for loads of ships - but the fact that she finds him adorable and hilarious and he enjoys that is just such a nice thing about them.
