I may have gotten some of the story wrong but if any of this sound familiar lmk
This does sound familiar and I tried to find it but I couldn't, lol. I think it was a coloured and short manhwa.
Omg yes it is
It's part of this series, the fourth one is the manhwa you're looking for: https://www.mangago.zone/read-manga/9733_s2/
Thank u so much
Welcome!^^
Ok I read this manga a while ago so I don’t remember much but I’ll try to explain as best I can but basically a guy was looking for something (I don’t remember what it was) and he found a cave w a mermaid in it and the mermaid attacked him cause it thought he was his grandfather. That’s the only thing I remember from the story
