are we really adding more

Can you explain the plot to me please

I like your user name lmao

So basically mc likes childhood bestfriend. One day he realizes that he is inside a novel and he used to be the uke inside the story but not anymore. Black-haired uke who knows the plot and is the new main uke seduces childhood bestfriend. Black-haired uke's bestfriend ( im gonna call him black haired seme) thinks he is in love with mc and sleeps with him. Black haired uke got transported into the novel and is using whatever means to survive. Coffee guy notices this and offers to help him. Coffee guy used to be the main seme along with mc as uke but got kicked to side character. He hates childhood bestfriend because he thinks that he stole the main seme position away from him.When he realises that he has the power to be unnoticeable as a side character visits mc when he is asleep and touches him without mc's knowledge. Oh yeah and childhood bestfriend also loves uke and realises he is in a novel too. Now that i read what i just wrote it has so much drama in it. Sorry if i couldn't explain it well , i have no idea how to convey stuff

Thank you thank you
