Yes

You speak in a tone to make it obvious your joking. "I did get a new pair of glasses, guess they where worth the money." She snickers before giving you a hug. "I missed you. I'm sure Sojiro wouldn't mind you just living hear with us, so do you have to go back after your vacation is over?" You hug her back. "Well I am 19 so my parents can't **** me to stay with them. So I would definitely be down with living hear. Although I don't think my future wife will be all to impressed with me living in an attic. Oh, I hope I'm not making you jelos." You try to use your power to make her ok with being in a harem. No dice. You see what you can do. You manage to change her cognition to think a guy haveing a harem is normal but you can't **** her to want to be in a harem.
