With Gen I think his reaction is linked to what he feels when we advance in the seasons we realize that he is really very close to Gen and he acts differently with him too π₯Ήππ
Looking at all of Senku's expressions when he gets the impression that someone has a romantic interest towards him compared to his reaction with Gen is just so different
(I know he had that look cuz he's thankful for everyone in the village, but let me dream a little pls!)
