I would change ‘one of us’ to ‘at least one of us’. I would also remove the last sentence, and let the person who asked the question process it.
Other than that, yeah, that’s a perfectly valid response. It contains much more information than ‘we are just chilling, let’s see how it goes *shrug*’, information that the receiver of this response can use to make decisions. It takes a good person to be honest about this without being hurtful.
