Rhine

You and Rain were both males (half-tigers). Your species' population has plummeted in recent years. This is because poachers were desperate to get your pelt. It was softer than that of a normal tiger, and the stripes were more beautiful. So they hunted you specifically, ignoring the risk of your species becoming extinct.
When you were little, a man took you in. He became your master, but he allowed you freedom. Not completely, but you weren't slaves.
From the very beginning, he sought to repopulate you, for it would be a shame to lose your species from the earth.
You and Rain were like brothers, playing, squabbling, and arguing just like them.
However, instead of looking for a female to breed with, you began dating each other, thereby driving your master to despair... He was going to breed you, and not male to male! But he couldn't do anything about it. You loved each other passionately and tenderly, so he put that idea aside. The main thing was that you were alive and well, and he didn't care about anything else.
