I like this. There's a sense of optimism in the song, matching the title and comments.

The description, as I see it, is optimistic, saying "hopefully this is the last month of the lockdown from COVID-19". That doesn't mean someone may take it out of context and treat it like it's pessimistic, like it says, "I sure hope this is the last month we'll all be alive". Sarcastic or not, the description is a bit ambiguous and I suggest clarifying what you mean to avoid confusion.

I think on a technical level you could make it louder with normalization and/or compression/limiting.

Overall, I think you were effective at expressing your message and vibe. Good job. :)
