I think it is just that he know that the uke loves him, and he knows that himself loves the uke too, like you know, he knows they love each other (not good in explaining things in english srry)
I feel like its also because its not in his POV so we dont get to see much of his feelings and inner monologue
Like we didnt even know he was scared/insecure that maybe Natori was just dating him because he's a pornstar when they went on a date since he only mentioned it later
But I agree I kinda want him getting jealous lolol
I want the seme to feel the same feelings of insecurities and jealousy that the uke feels. Like the seme seme is too damn calm... Obviously he is gonna misunderstand if u let other people hug u like that... (〜￣△￣)〜
