You have a merman friend. He is Ayato, you met him when you were walking around the beach alone. He's a really nice merman, he's friendly and curious about a lot of things, it's adorable. But he only allows you to play with him during the day

One night, you want to meet him and tell him something important. you saw him sitting on a large rock, you approached him, patted him while calling him. but when he turns around and faces you, you see he's... faceless
