Even though they were arguably the most popular members at RV's prime, they could end up becoming the least popular members among the GP by the next comeback.
Irene is still embroiled on her power trip scandal which means she barely updates on social media (albeit is not fully silent like in the past). She is the member with most fans but that won't do anything to her because there is no content for these fans to buy: she won't drop a solo, magazines blacklisted her and she's a persona non grata in korean entertainment circles. The group is the only thing left for her.
Seulgi on the other hand remains popular in the industry, but SM has basically forgot she exists. While Joy and Wendy have become the most prioritized members, with the former landing a new drama, scoring multiple OSTs and having a daily TV show while the latter gets to host a radio show and both having a solo, Seulgi got passed by. No wonder she ranked last on the group in the brand reputation index when RV had a comeback, she became a forgotten member even in comparison to Yeri, who's starting an acting career, while Seulgi only gets a few photoshoots here and there and an online radio show only her fans tune in.
