how she hasn't noticed she lost her ring

What are u talking about o: she noticed right away and now she's keeping it in the box

didnt the other girl find it? i think i have to re-read

Yes, but Sooha came back right away and asked her to give it back

I think cause she wasn't used to it yet and it wasnt a habit of hers to check on the ring every time, happens to me and my class ring all the time before...
good thing no one randomly picked it up and tried it on, like who does that??? Oh wait...
