Park Shin Hye may spy on beautiful boys in Flower Boy Next door, but she's the one getting spied on in So Ji Sub's comeback video teaser, "Eraser," featuring Mellow. In the video, a happy, dreamy Park Shin Hye wistfully brews coffee when her phone goes off. The call goes to voicemail and the voice (So Ji Sub) startles her. He calls her honey and asks what she's doing, he then says I'm waiting for your call and that he's in front of her house... Looks like the tables may have turned, as this time it's Park Shin Hye who's being watched! Check out the teaser below: Are you looking forward to So Ji Sub's comeback video now that Park Shin Hye is in it?
