Lovely Runner or Perfect Crown?

Im an avid fan of Lovely Runner to the point I bought merchandises I really love BWS and KHY and I tried to watch KHY romcom drama after LR and its not the same feeling when I watched LR. While BWS and IU drama I didn't watch it until now just some reels on Instagram and don't know I'm not into it I guess Im too hang up with BWS and KHY. I really like IU but whenever I see some clips on their drama it feels like its not natural unlike in LR. Is it just me or does anyone felt the same.
