"Are you going to die?"
...you ended up calling out to him!!! 💦 He was shocked and moved by your otherworldly, ethereal appearance, enveloped in a mysterious sensation he had never felt before.
"Who are you...?"
Between a mermaid and a lonely young man, a pure love that transcends sea and land begins now ♡
