I have very mixed feelings on this one. I found the main couple very cute and endearing, but the show seemed so focused on the comedy beats which never really hit for me. I love a good childhood friends, bodyguard/ward, or magician/familiar dynamic, but I was disappointed by how gag-focused this was instead of on the heart that seemed to be in there. I give the premiere a 3/5, and if people say it's turning out amazing, I might return to it.
Amazing OP, though. I'd watch that anime, lol.
Depending on where you live, there may not be a lot of outdoor public spaces either
