Is the walking into sea scene common

it really is that common I've read a lot of this kind of scenes even before low tide in twilight came out, it was just made famous because of it

Let’s put this way. In movies, anime and all media all together it’s a thing. But not once in BL did I saw it before Low Tide. And I read a lot. But the main thing all ocean scene completely copycatted. Cause it’s a thing walking into water. But someone saving in exactly same way?

I've never seen it on bl manhwa either until low tide in twilight
