The summary makes no sense

As far as I read. MC an average guy from S.Korea , an ace employee when it come to part time jobs , transmigrated to a bl novel he read . He became a side character who is an author , and got killed by the og novel top . Now to escape from his death he tried to deny the og bottom's request to ghostwritting love letters to the top. But by the given circumstances he ended up as the bedchamber maid of the top and taking the request of becoming ghostwriter for og bottom. Read it , it has a good premise

Thanks so much! I’ll definitely read it.
