Ong Seong Wu is one of a few K-pop idols who starred in a K-drama and sung for it’s original soundtrack. Similar to what ASTRO’s Cha Eun Woo had done in 2018 where he starred in “Gangnam Beauty” and sang one of the show’s OST.
The former Wanna One member recorded “Our Story” and you can hear it from time to time as background music to his critically-acclaimed school drama “Moments of 18” (Sometimes titled “At Eighteen”).
