This is Seo In Kuk's second No. 1 on the K-Pop Hot 100. He earned a three-week chart topper with "All for You," another duet, with Apink member Jeong Eun Ji.
Just below at No. 2, Lena Park's "My Wish" rises from No. 5. An original soundtrack single off popular Korean drama "The Heirs," the song is a slow, heart-wrenching ballad featuring lyrics lamenting the inability of two lovers to be together.
Aside from Lena Park, other tracks from the drama soundtrack charted this week: Lee Min Ho (the lead actor for the drama) sent his "Painful Love" single to its No. 10 debut, while 2AM's Changmin and his previous Top 10 hit "Moment" drops to No. 36 this week from No. 33.
At No. 3 is yet another soundtrack single, Korean folk-rock singer Lim Kim's "Happy Me," lifted from the soundtrack to Korean drama "Reply 1994." Piano chords and scales, along with a light-rock production, accompany the 19-year-old's unique vocals fluttering from strong chest voice notes to airy head voice.
