It’s about him getting a job offer where they promise him food, accommodation, and even a lover. but when he gets in the game he is constant dying trying to solve it. He dies by the butler because he didn’t come out of his room?!(not sure if that was in the synopsis but its similar) he dies from the littlest of mistakes. well it something like that. If you know it tell me (^◡^ )
The Target Always Thinks That I Like Him? Is it this one? The synopsis matches what you're looking for. I haven't read it but dieing from little mistakes and a butler also reminds me of Game Loading lol
Entering a Split Personality? He gets promised a job that offers food, accomodation and a lover (not sure, been a while since I read it). When he first started the game, he does die from little mistakes (kind of). The butler and him dying from little mistakes screams more of Game Loading, though.
