Whiners gonna whine, nothing new. Yes author pretty much gives one pointless cliffhanger after another, but it's on reader to take or leave the bait hanging.
This is pretty much a "imagination vs reality": the chapter, if you don't say something - nothing going to happend.
After premier of movie there will be pretty much no connection between them, she's a fresh star (if it's succeds) and he's an amator producer, they're neighbors, that it.
People shit on mc alot because he's "simp", but he's a virgin with 1 unsuccesful relationship behind. Yeah there is Ruka but she's only intrested in him as reason for hear heartbeat, not really into what mc is or what he likes. Don't take me wrong, yeah mc is pretty spineless when it comes to conveying his feelings, but did show multiple times that he can act like he has balls, jumping from ship, breaking up and etc. Damn he even crowdfounded a movie for FMC.
Meanwhile what has FMC done? Protected mc in eyes of his ex-girlfriend, cpr in early chapter and... oh right "I do not not like him" and "thank you"... sheesh alot of action on this one. Maybe I forgot something.
But at this point not even Mami is going to change anything in those dynamics.
@LeEpicMinecrafter go read Kaguya-sama, there is definite progress.
