like when he goes to sing a album with Miley Cara. She's a famous singer. So you would expect the recording session to be heavily or decently detailed. No all the author really says is and I quote here. "12 hours.

That was how long Woojin spent in the recording studio. From early morning until the afternoon, Kang Woojin was fully immersed in the recording sessions with Cara. Meanwhile, back in Korea, the night had passed, and it was now morning." like wow this is disgusting. The author chooses to forego explaining how the MC will sing in favor of reactions from the general public for the mc's anime work.

MC finally revealed his actual self to everyone with his speech and Miley just had to yap, "Oh. He's just acting." Like shut the f**k up, b*tch? SHE can't even listen to his side as HIS GIRLFRIEND. MC already told her about this before and she just brushed it off as nonsense. MC then gave up explaining his situation after seeing it was useless for him to speak up 'cuz cycle repeats. So he lived a very long life acting "cold" and "emotionless" with no one, aside from his family and friends before, who really understand his true self. What a pity. A great work ruined.

of how it basically rips off blockbusters from real life (so it starts to feel like a self inserted fan fic).

I get that there are jealousy of the MC in the first place, but there were barely anything in the "first parts" of the Protag's acting career being jealous that a newbie gets hired immediately with barely any audition. There's only 1 instance of a Korean being jealous and then she quickly disappears, but shouldn't the Protag face more struggles in his own country first before the second one?

The formula never changes. The much-anticipated Hollywood projects Woojin does are literally just lazy rip-offs of existing movies the author personally liked (Joker, Beauty and the Beast, and a John Wick/Jason Bourne mashup). The same thing happens for every movie: the same internet comments, the same strange nationalistic racism, the same shock that the good actor is still a good actor. No one ever looks at his filmography before assuming he's an overblown hack, and no one is even tangentially aware that they can view foreign content on the internet. Everything is lazy.

But the biggest problem is the romance, because that could have been this story's greatest strength (and SO easily, no less). Why do Korean stories always set up early love interests and then never use them? Hwarin was entirely sufficient, but not glamorous enough, so she was thrown away in favor of the Miley Cyrus knock-off... fine. Whatever. Your protagonist lives his life pretending to be someone he's not. He lives a lie, both in his opinion of himself and in reality... but whenever he tries to step out of his persona, no one believes him. That is a soul-crushing way to live, man... and the author seems to understand that, and he tries to get the story to culminate in some sort of relief for Woojin, but he SUCKS AT IT. Do you know how the main love interest *should* be introduced? She should look at him funny and say, "Why are you acting so serious? Just be yourself. Have dinner with me. Chill." That would give the character an emotional outlet and endear the love interest to the audience. 'At least one person in the world actually understands me'. Instead, the author has her, his girlfriend, explain to the other celebrities around her, as he's trying to explain his reality to the world, that he's accepting the Oscar IN CHARACTER AS A PSYCHOPATH. Woojin then promptly gives up being his true self ever again. The end. I kid you f-ing not. The author tried to do some sort of time loop thing where he went into his subspace and experienced himself in his life story or whatever, but it was weak sauce. No one cares how he got his system, author. I know you've been dying to over-explain your genius plot device or something, but literally no one asked.

Because you need some mental strength if you keep living the actual lives of all those characters
