Blue would 100% try to pay for every meal cause he wants to be a "good boyfriend," but he is NOT the best at money management and Mulberry would have to step in to explain like, hey we can do 50/50 and like talk about what they can and can't afford. Like i cant fathom Mulberry caring about big expensive dates, but Blue would kinda just assume "oh good boyfriends do those big flashy displays" he is a silly guy LOL
