TEASER #2

This time the teaser will be slightly harder and you'll need to think hard about it...

My new fanfic will have three of the Super Junior members as the main characters, here are the clues. Each standing for ONE character/member.

Clue 1: Memories

Clue 2: White Christmas

Clue 3: Y

Hint: Have a look at the official order of the Mr. Simple tracklist...and remember, 13 members=13 songs *wink wink*

Feel free to post your guesses below~!
