I am going to ask this guy to hang out alone... We have been friends for a while and hung out alone but not as a planned thin. just deciding what i will suggest we do. These are all things I like to do and I don't think he will mind any of them as we have similar taste and they are low key.
Museum is the best place. You're chilled surrounded by art, there's no loud ass people around you so you can get to know each other in a super casual way while you see art. It's amazing! You can take him to the park on the second date tho
