Recently, Tei and Kan Mi Youn did a photoshoot together as a couple. The photoshoot was for their new duet, '7 Things I Promise You.' The concept of this photoshoot was 'Lovers,' and the two surprisingly pulled it off really well. The portrayed chemistry between the two almost seems too real. An onlooker stated, "Although this was a concept Tei has never gone for, he pulled it off very well, like a pro. You can definitely look forward to this." Their duet has already entered the music charts, taking 1st on Bugs Music and 4th on Cyworld.
