On July 18th, Trax's Jungmo uploaded the above photo with the tweet, "Giving BoA a guitar lesson." In the photo, BoA is seen with a guitar at what appears to be one of SM Entertainment's practice rooms. Super Junior's Heechul also tweeted a separate photo from the scene, saying "Guess who?", to which BoA responded, "Oppa your pants!!!!" The picture shows the reflections of Heechul, BoA, and Jungmo in the mirror, and while BoA and Jungmo seem to be concentrating on their guitars, Heechul is busy striking a pose and taking a picture with his phone in his outrageously hot pink skinny jeans. We're sure fans would love to see BoA show off her guitar skills in the near future! Source + Photos: Jungmo's Twitter, Heechul's Twitter
