Rheus appears tough and ruthless, but deep down, he's quite different. He doesn't understand emotions and love well, even though he's feared as a mafia boss. Despite this, he has many gentle qualities that are often overlooked. He's innocent in some ways, which can be surprising given his tough exterior. People often misunderstand him because they don't see his softer side. He can be quite dramatic too, especially when he's feeling emotional or vulnerable, especially when it comes to jealousy.
