Glad to see JQ back to uploading chapters here on Mangadex, especially this manga that's still one of my favorites (and, ofc, this was super cute chapter, as always).
For those that are confused the mermaid was never real. It was just a coping mechanism for Shou to help her deal with the loss of her mother. The splash at the end is to just symbolise that Shou has finally been able to move on.
Come with me, lesbian seagull
Settle down and rest with me
Fly with me, lesbian seagull
To my little nest by the sea
With me, that's where you belong with me
I know I can be strong when you're with me
