The voice was singing a haunting melody, sounding ethereal. It spread itself like a blanket over his mind, clouding it and making it pretty much impossible to think as he blindly followed it to the water's edge
He just-couldn't think at all. It was like a cloud that just-blocked thinking. Katsuki had clearly told him to not go near the shore, but it just..got out his memory. His mind went blank, the only thing he could think about was the voice. That's it.
