Heo Young Saeng filming for a new Music Video?

I know you are curious about the song that will be used. Well, this is not official, but I heard from someone that it's for 'Rainy Heart'. It has not been confirmed nor denied by his agency, but one thing is for sure, we will be anticipating this MV. ^^ (I hope Kyu Jong can be featured if it's really Rainy Heart)
