That wasn't the beginning of their chemistry it's been like that between them for years. Checkout any videos with the two of them and you'll see that they've always been close. SunSun used to be the talk of the K-pop world but now it's HenSun/SunRy(I). Their chemistry is as real as the ground we walk on. They're amazing together in talent, spirit, appearance and everything. I want the headline "SNSD Sunny & Super Junior-M Henry Lau announced their Engagement!!!" SO BAD.
