There definitely should be a S3 to finish their senior year and more closure to what happened at the end. I think the gang will pair up with Seong Je against the bad boss if he was responsible for Baek Jin.
I think the current top 7 is great and it honestly has not changed and donāt think it will. I would just have either Dong Dong or Yuchen instead of Zihao imo.
Edit: Finished the season in 1 day. Thatās how good I thought it was.
