Ryuusei is shown to be very comforting and understanding. He likes to listen to people's problems and help them through it as much as he can, which is shown when he talks to Ema after Kaname and Chiaki run off to help customers.
They are shown to be on friendly terms.
They work in the same place. They do get along well with each other.
