The final single from I.O.I, Downpour is a euphonic ballad produced by SEVENTEEN’s Woozi.

The song tells the year-long story of I.O.I, their hardships since their trainee days, the memories they have cherished, and the achievements they’ve reached as a project group. The 11 girls poured out their hearts to perform this song for the first and last time at their concert, ‘TIME SLIP’ which sold out a few moments after ticketing was open. Thanks to the fans, their achievements and the love and support they’ve received, I.O.I remains one of the greatest project groups in the history of K-pop.
