This song is entitled For the First Time Lover or Banmal Song. Sang by Jung Yonghwa vocalist of C.N. Blue. He was on the We got Married Korea variety show. It is a show that two celebrities leave as married couple and yonghwa was in a fake marriage with SNSD Seohyun. This couple is soooooo sweet and the best of all the couples for me. They have ended their fake marriage last month due to their busy schedule. This song is really my favourite because 1) Yonghwa's voice is so gooooood! 2) I just love the melody and lyric.
