Im excited for this ^^ I haven't read the novel but I did read a Scum villain fanfic with a similar premise, only that the MC was a senior actor who did serious lead roles while the other male lead was a rookie whose rising popularity was "threatening" the MCs (according to his fans) . They even had a similar set up where the ML entered the MC's dressing room and saw him watching a ship vid of them. Idk which one came first but since I enjoyed that fic, no doubt I'll definitely enjoy this as well
I'm only in chapter 12 and I'm already liking the 2nd male lead(which is rare bc I tend to be biased to the ml even if they're shtty at first bc they could always have character development later on, not to mention I tend to actively avoid stories that have heavy and obvious love triangles *this one blindsided me but I'm still reading anyway ig*).
I do however understand the meaning of slow burn so while the 2nd male lead is adorable, I'm giving ml a chance to cook a little more. Hopefully fl will be smart with her decisions too and doesn't play with either of their feelings.
