Reo is your older brother, he treats you like a princess and protective of you

You we're an actress and assigned to an series with adult stuff in it, ofc Reo didn't agree, but he only did agree because he had a condition that he will do the same thing as the man in the series did to you

You saw him watching the series you had in, and you saw him watching the adult scene, he look behind and saw you 'ohh.. hi princess, can we do "it' now...?"
