Rumored Queendom S2 lineup - Update with 2 new girl groups

I'm believing in StayC and WJSN on the line up, because they suddenly started/will start to promote on MCountdown this year

Seeun said stayc is not going on queendom

it's like an advent calendar, but everyday is a new queendom lineup

Quote from SafariDebut

Oh really. I knew that boyfriend being mad at his girlfriend who works at Mnet and then revealing the lineup doesn't make sense to me

On the other hand, STAYC is confirmed to attend Mcountdown which might mean they could be on Queendom.
