Well, I have a running gag where I (dressed as Ash Ketchum) propose to any Pokemon cosplayer I think Ash would be paired with/I like/if I haven't proposed to that particular character yet/if they ask for a proposal. They also get to keep their rings (I buy cheap rings for this purpose). Anyway I proposed to this White in a previous picture and she used her ring to stage this photo. I don't actually think Cheren was expecting it, but she was planning on doing it after she saw me proposing to other cosplayers. So yes, she really proposed, no, it wasn't an actual proposal, and I'm not sure if it's a staged reaction or not. You'd be surprised, a lot of people react in ways that look fake on camera when you surprise them XD
