Perfect night isn't a comeback, it's just a song for overwatch ... anyways considering their last comeback was in May, that would mean it's been 6 months, there is only 1 month left for the year and barely anyone makes December comebacks, so I'd highly doubt they'd comeback in December, so if their next comeback will happen in 2024 wouldn't that mean that would be a pretty long gap between comebacks for a new group?
It's interesting they only had one comeback this year.
