This was beautiful. Kazushi (the seme) and tatsumi (the uke) meet when they were kids on the beach. They grow up together as best friends and are inseparable. The seme has always loved and been in love with the uke. The uke has a special power (the seme calls it the power of suggestion) his voice sounds like the ocean when he uses it and he persuades people to do certain things. He's scared of the power and that he'll use it on the seme so he tries to make the seme forget him. The meet again later and he finds out his voice doesn't work on the seme. They get together. There is no smut. Just fluff and chest aches
See you later, Mermaid
