Roommate with my Boss

Boss, roommate, fake fiancé… real lover? Étienne is cold, charismatic, and he never shies away from a challenge. He masters everything down to the smallest detail… until a little accountant with an unlikely look and flowers in her hair inserts herself into his daily life. She is whimsical, full of life, laughs at the rules and gets around them, talks all the time except about her past… and she drives him crazy. Yet, it's impossible to fire her. She needs a job and a roof over her head; he needs a fake fiancée... Is it a deal?
