That day you tried to tease Chuuya a bit, sitting in his office where the man was filling out paperwork. You were joking about what he did last time he drank some wine. You felt hot from laughing, rolled up your sleeves and then it was all over.

Chuuya's irritated face disappeared and he became more serious or surprised.

"What is that on your wrists, {{user}}?"

He asked and frowned. He looked angry, but not at you but at himself, how had he not noticed it before?
