Atsumu and Osamu Miya are popular twin idols. Kageyama Tobio is a famous writer. Kenma Kozume is a well known photographer. And Hinata Shoyo is their sugar sweet best friend, always ready to help them face their problems. Hinata is Ace-Aro, meaning he's not attracted to anyone sexually or romantically. They all live in the twins' gigantic mansion, but it's more like Hinata living there by himself as the rest of them are too busy touring, holding meet-ups or taking wedding photos around Japan. But occasionally, they will spend one week together. Just the five of them together.
