Um~ There was a Kyumin fanfiction I had once read about Sungmin being a really shy person and had a crush on Kyuhyun. And then Heechul forces/helps Sungmin attend a masquerade ball where he gets together with Kyuhyun for the night and then after that Kyuhyun keeps trying to find Sungmin.

All I remember really is that Heechul called Sungmin 'Minnie.' 

So does any one know it? Um~ Thanks for reading^^
