Amazing timing with the comebacks. Fans would say it's "bold" to let IVE, a rookie group, come back during the August bloodbath, but I actually think it's great to capitalize on the hype. The fact that fans even mention IVE as part of the bloodbath means they'll check out the song just to see what it's about.
Starship let IVE come back during BIGBANG's "Still Life" ordeal. They're doing it again this time, and the results will be even better.
EXO's Chen was right. There really is no competition in music. There's only collaboration even if indirectly through marketing tactics like this.
