I.O.I’s highly anticipated reunion comeback is already receiving mixed reactions online.
After years of waiting, the legendary project girl group recently dropped a preview of their upcoming title track “Suddenly” through a dance challenge clip, but not all fans are impressed.

While many were emotional simply seeing the members together again, others admitted they felt disappointed by the song snippet itself, saying it lacked the impact they expected from such a major reunion.

- Even the album cover is ugly.
- The song is so old-fashioned…
- Sigh… I had high hopes… Ugh, it sounds too much like trot.
- The tempo is too slow…
- Ah, this isn’t the title song, right? This isn’t the I.O.I we were waiting for.
Others even claimed that they were hoping for something that sounded a little more like “Very Very Very,” a song considered the peak of I.O.I. The choreography preview also sparked discussion, with some viewers feeling the challenge lacked a strong killing point or viral moment.
However, many fans defended the group, arguing that the short preview may not fully represent the final song. Despite the divided reactions, the comeback remains one of the most talked-about idol reunions of the year, with fans still eagerly waiting for the full release.
