It was an awful song choice; it really was. I don't think they waited long enough since Bo Peep Bo Peep either. There wasn't enough buildup and, once again, it really just wasn't a good song choice. I'm talking about it like it's an enormous flop, which it obviously isn't, but it's not a great (first day) position compared to BPBP or even most other Japanese releases by major K-Pop groups. They just have so many better songs they could have picked. I can't even imagine how incredible Wae Ireoni could have been in Japanese
...not that there isn't still a chance of that happening
And what the hell happened with the Black Eyed Peas?
