Looking for this BL manga

Hi looking for this bl manga that I've read, I don't remember if I even saved in this website list..Here's what I remember:

The setting sets up in modern Japan, mc has white hair and currently works as a novel writer. He used to be some war general who had a thing for reading I think but apparently was forced off into war at the time war was happening. I think he was a elf or something I don't know. MC likes reading books so much in the past life and this life too. While the ML is black haired and he works also as some manager relating to some role in the book industry where the mc also works at. The ML also knew the mc in the past life where war was happening as he was on the opposing side. Both of their past lives were in some war and it was fantasy with magic and elves exist. While in modern day japan the mc is trying to avoid the ml due to their past lives while the ML like the mc

That's all I could remember T.T
