I read this a month or two ago and have completely forgotten he title. Protagonist is transmigrated into a small star/idol while a reality show (village life thing) is being filmed. Original got a cold. Protagonist knows martial arts. The manager of star/idol wants protagonist to play like a lazy person to increase bad rep to get more popularity. A scene that stood out is he caught a lot of fish and gave it all to one of the other actors.
Ohh I know it but I forgot the name!! I’ll look for it for now... Never mind, the one I read wasn’t bl! And you’ve already found it..
