Offer her some 'assistance'.

You sympathize with Hedieh. It wasn't long ago that you, too, wished you could blow off work and mess around with your friends while still living with your parents. Right now, your only wish is to take this girl and teach her how to be a grinning, drooling slut, and you think that you can both benefit. When Horiya comes back, she informs Hedieh that her father is going to going on a business trip starting tomorrow, and you take the chance to offer to assist in Hedieh's studying. You tell Horiya that you have some background doing tutoring work while at college, and that you can probably raise Hedieh's scores by a few percentiles. She's grateful for your assistance and appreciates the spirit of neighborly kindness. She heads out to the garden again so you can get more oriented with Hedieh.

It turns out, she's doing about as well as a girl can in academic matters. She's a bright young thing, but her parents don't know when to let her kick back. She flips through her study text and shows you the practice tests she's been acing, and you take the chance to sidle up closer to her.

"This is really impressive, Hedieh. You must have been first in your class before you got pulled out."

"Well, I was, but it wasn't exactly difficult. All the kids at that school wanted to do was skip class and make out." That does sound like your old school. "Right as I was leaving, there was a bunch of new rules and stuff getting brought in. They really wanted kids to, like, be free and open, but mostly they were just doing more of that. I never really cared about it, they can waste their own time." She's trying to play off her frustration.

"You sound like you were missing out. Are you jealous of those guys? Did you have a boyfriend?"

"Not a boyfriend, but there was a guy, well, a few guys, that I was sort of into... Not that they'd ever notice me. They all had their own girlfriends. They were worthless sluts."

"Whoa, pump your brakes, Hedieh. That sounds like your mom talking. It sucks your parents wouldn't let you get to know those people, but let me tell you, being a slut is nothing to frown on. If you get down on other people just doing their own thing, you're just going to get more and more wound up." She sighs.

"I know. It's just that, well, I still feel like I ought to try and be the daughter my dad raised. But I really do want to be like those girls. They always looked so happy with themselves. I wish I could feel like that, be really in control of my own body. But that's why I have to pass these exams!"

"Okay, okay, Hedieh, you're getting into a cycle. You can relax now, I'll cover for you. This week, you and me can go hit the town, I'll tell your mom we're at the library. You can cut loose and be however you want to be."
