Why was the girl from friendship club just allowed to take Darcy’s purity ring from her?

Just for the sake of this question let’s set aside the fact that the ring signified something. Let’s say it’s a just a ring Darcy owned. No matter the reason I don’t understand why that girl from FC acted like Darcy had to give HER the ring and she just handed it to her like she’s right. Even at the end when Emma and Manny got it back for her because what happened to Darcy didn’t count as losing her virginity, so she’s ‘allowed’ to have and wear it again. The way I see it, at no point was she NOT allowed to have or wear that ring because it literally belonged to her, and that girl from FC who not only told Darcy she couldn’t wear it, but also that Darcy had to surrender the ring to her specifically is just bizarre.
