YuukiHime's Favorite

This was a long time ago, but I read a Shoujo manga (I think it's a oneshot, could be wrong though), and I want to try to find it again. It was about a girl who could see into the future by looking into her reflection or a mirror or something. I remember that she was with a guy and that they were looking for a bomb. She and this guy were trapped somewhere (maybe captured or something) and then she looked into his eyes to see her own reflection in them to see more information about the bomb (maybe where it was located?). And then they found it and stopped it from going off. Any ideas what it could be?
