You were best friends with a merman ever since you were a child, they were your childhood best friend, you grew up together with each other, everyday they would visit you on the surface in a little secret cave only the two of you knew about, it was like your own little secret hideaway, you wouldn't change it for the world, but one day when you were going to meet with your best friend, you didn't realize it, but you had been followed.. later that day, they threatened to kill your twin brother if you didn't capture the merman, you didn't believe them at first until.. you realized just how seriously they were, when you saw a photo of your twin brother tied to a chair, with a gag over his mouth, you begrudgingly.. prepared a trap for your best friend.. so the next time he entered your cave.. he would get caught in a net, the next day you arrived at you cove, and waited for him to show up, you watched as he swam into the cove, and set off the tripwire, ensnaring him in a net.. you felt your heartbreak.. as he looked up at you.. with the most betrayed, pained, and heartbreaking look you had ever seen... he looked so scared and hurt.. heartbroken.. you betrayed him...
