Project girl group I.O.I have released their last single together.

The song, titled “Downpour“, was personally chosen by the members and it was composed by Seventeen‘s Woozi.

The music video shows the group’s memories together starting from “Produce 101” to their debut days.

This is really sad news for the fans all over the world who got attached to the 11 talented girls. Although everyone knew that the group will only last a year, the news of disbanding are more heartbreaking than expected.

However, you can still see some of the girls in other girl groups, while the others will debut soon.

I.O.I’s leader NaYoung and Pinky will debut very soon in Pristin (Pledis Girlz), the upcoming Pledis girl group, Kim Sejeong and Kang Mina have debuted in June last year in Gugudan, in July Yoo YeonJung has joined Cosmic Girls (WJSN), who debuted in February last year, dance machine Kim ChungHa will be the only I.O.I member to make a solo debut, Jung ChaeYeon will continue her activities in DIA, Choi YooJung and Kim DoYeon will debut in the upcoming Fantagio girl group, Kim SoHye will focus on acting and variety shows, while 1st place Jeon Somi‘s future is still unknown as JYP has recently debuted TWICE.

Moreover, on January 20, 21 and 22 I.O.I held their last concerts ‘Time Slip‘ at Jangchung Gymnasium, where they made their official debut.
