The video has Lee Joon stuck between Lee Se Young and Oh Jung Sae, with the actress whispering in his ear to suck while the actor tries to dissuade him.

The idol turned actor gives in, sucks the blood, and crushes the glass with his hand. Lee Se Young and Oh Jung Sae taunt him, with the last couple seconds of the video showing all three trying to hold in their laughter at the hilarity of the teaser video.

It's all very seductive and sexy, with the theme of vampires reminiscent of Lee Joon's MBLAQ debut song 'Oh Yeah.'

Lee Joon plays the role of Yoon-San, an irritable detective that suddenly becomes a vampire in the fantasy-action drama.

The show is slated to begin March 27th.

Are you ready for Lee Joon's return as a vampire?
