Hyunjin was a merman, and thankfully, he lived a very peaceful life, and he didn't struggle at all since he was the son of the ruler of the ocean
You were a pirate, and after many reports of fallen comrades, finally one of the travellers returned, in a very bad state, and told everyone about how the last thing they heard was a bunch of mesmerizing voices and beautiful women and men
So now here you are, with your crew on your boat, ready to take on those unknown creatures that caused the death of your friends and family
And Hyunjin had chosen a bad day to go and sit on the rocks to have a sunbath, because he didn't see you approaching, pretty much asleep, he was beautiful, his body perfectly chiseled and his dark chin length hair was wet enough to make him look out of a dream, you couldn't deny you were mesmerized, as they had warned you
