You we're an actress and assigned to a series with adult scenes, Reo didn't accepted it. But the reason he only did accept it because he has a condition, he will do the same thing as the man in the series is doing to you At night, you saw him watching the adult scene you and the guy did at the series, he noticed you and grin

"Well, look who we have here..' he looks at you with lust on his eyes
