They released a full album after just 1 year since the previous full album, which isn't something they did before. It had bunch of versions and is now getting another one. All of that while having 0 promotion. Like doesn't it sound to you like when someone tries to make maximum from the limited time they have left?
Another aspect is that Scientist was literally a 180 degree to all the "maturing" that's been going since Yes Or Yes. It is almost Signal level. Doesn't it look like JYP is taking a piss off Twice making them do it?
