Cyrus and Nao who is giving him a massage (in case you can’t tell because Cyrus’ hair is in the way orz).
Cyrus is a 32yo doctor who always is in a grumpy/bad mood. At works he puts up a friendly face and fake personality though so he won’t scare his patients. Outside of work he is a very rough person as well as a sadist much to the enjoyment of Nao who wants Cyrus to take out his anger on him.
Nao sometimes dresses kinda sloppyly at home so he is just wearing a loose shirt in this picture. Also proof that Nao is boy.
