Girl's Day's oldest unni Sojin is sharing the love to the maknae Hyeri, by taking part in an OST for Hyeri's drama 'Reply 1988'!

Dream Tea Entertainment's side revealed the news on December 24, and added, "She will sing "Everyday Be With You" (literal title). The song will come out on December 25 on Christmas night at midnight (KST)."

"Everyday Be With You" is rock group Deulgukhwa's 1985 hit song, and like all of the other 'Reply 1988' OSTs, Sojin will be singing the remake.

Their company added, "Sojin is super happy that she's able to sing an OST for the drama Hyeri is acting in. Sojin is also a huge fan who watches 'Reply 1988' on broadcast."
