Ryu arrived just in time when everyone was packing up.
Arya actually wanted to introduce him to the staff and crew but he refused. He wanted to support Arya's career because he saw how excited she was while she practiced her lines with him.
But he wanted her wife to be acknowledged for her hard work and capabilities and not get herself labelled as a Ken and let the media drag her down because she had a Ken in her name.
They will judge her for getting the role because of her connection with the Kens.
He wanted to keep their marriage under folds until the drama airs and the people saw how talented his wife was.
So he waited inside the car instead and called Arya.
After waiting for a little while, he saw Arya smiling widely walking excitedly towards his car.
Seeing her smile like that, wearing a bright casual dress, a little above her knees made his day already regardless how tired he was.
