As reported earlier, Super Junior's Yesung and f(x)'s Luna teamed up to record a duet track titled, "And I Love You", for KBS's "President, OST Part 2". The full track was released recently, and as intended, the combination of the duo's rich vocals and stirring melody really bring out the song's purpose as the drama's "love theme." Achieve Group DN, the production company for the OST, commented, "The harmonization of their voices was exceptional. The sad melody and emotional lyrics mesh well together to create a luxurious ballad track that will surely be the best of this winter season." Check it out below!
