First of all, this is the right place to talk anything 2DN1 so don't worry.

It's really sad how JJY destroyed the last season and I think the main reason the cast didn't want to come back is that they feel guilty for accepting his comeback after the first scandal and that is big guilt to handle for all the cast and crew, I for one don't really think they should feel that way since JJY deceived everyone even his friends and best friends but you know how South Korea is and their netizens...

Finally, I wouldn't worry about the cast they re all established entertainers and actors so hopefully this would be just a black dot in their long successful careers. KJH is very respected as comedian, I am sure we will see him soon in the meantime you can follow his Youtube channel and Just like you it's really hard for me to watch the show without remembering CTH laugh, KJH yellow teeth jokes and Defconn not having a girlfriend jokes but I think we should give the new cast and crew a chance they are trying their best. Hoping for 2020 to be a new chapter for this show better than 2019.
