Day fifteen: A SJ song that reminds you of the missing 3

It had to be Bonamana. Whenever I hear it, I immediately remember that the missing 3's voices aren't here. :(

Day sixteen: The very first SJ song that you’ve ever heard

Sorry Sorry.

I heard this song when me and my cousin talked and she told me how handsome the members in Super Junior are. And me, being the curious one, searched for their song. :DDD
