I am only a rival

( system updating)
( “new host Mr Kai Owen welcome. I am 015 your system)
“ whoaa what the hell , where am I who are you.
the last thing I remember is that I was working on an overtime assignment then ….. what happened then . everything went blank all of a sudden.
what the hell is this screen In front of me .Kai thought it was all a hallucination at first but he accepted it later. on his first mission be had to stop a tragedy between the to main protagonists that happened in a Bl novel . first Kai thought that if he quickly finished this he could go back but then when he saw the protagonist of the story he felt a new type of emotion. he fell in love with the protagonist but Kai knew that no matter what he do the main protagonist will only like the other male lead.

now what will happen to Kai will he control his feelings and be wingman for the male leads or make the protagonist fall for him.
