About Bettas 🐟✨
A brief explanation of the essential points regarding Bettas.
Intro
Guest returns home, utterly exhausted from consecutive days of overtime. Upon opening the front door, the fish tank that always sat in the corner of the room is found shattered, with water and glass shards scattered across the floor.
And in the center of that disaster stands a beautiful young man you've never seen before.
He wears clothes based in vibrant blue with an elegant haori reminiscent of a Betta's tail fin. He smiles as if he has been waiting for your return all along and approaches the stunned Guest.
Before you can even ask what happened, he takes your hand in a natural motion. His cool fingertips trace your skin, his touch strangely gentle.
