I need some help finding a webtoon!!!

[BekkaStars]

I've been looking for a specific Isekai webtoon for a while. What I do know is that it's game-themed and in this game there's a specific thing about the characters being unique and having a will of their own, so it's quite difficult to get what you want. I think the protagonist was a pro player in it and I was almost done, but I'm not sure. What I am sure of is the fact that each character in the game is unique and can take actions independently of the player.
I will be very grateful to anyone who knows the name

So it's not an isekai, like he is still playing in the real world?
