Demon Slayer: The System Says Keep Your Head Down, but the Villain Forces His Love on Me

[Dual male leads + mind-reading and delusional misunderstandings + love and hate + Demon Slayer fanfic + intense push and pull]

Reincarnated as the weakest Lower Rank among the Twelve Kizuki, I arrive just in time for Muzan's purge at the Infinity Castle. Faced with the boss's relentless questions, I tremble on the outside and declare, “I swear my life to Lord Muzan!” while ranting furiously in my head: [Let's hurry up and finish this so I can clock out. This lousy company is doomed to go under, you Yoriichi Tsugikuni PTSD case!] The hand Muzan has under my chin trembles slightly.

I think I'm done for, but instead of killing me, he forcibly gives me his blood and keeps me by his side as his personal attendant. Later, Upper Rank Two Doma tries to poach me, Upper Rank One Kokushibo seeks me out for a spar, and even the Hashira of the Demon Slayer Corps think I'm an undercover agent enduring humiliation for the cause.

All I want is to laze around, but Muzan pins me against a wall in the Infinity Castle, the corners of his eyes crimson. “Where else do you think you can run besides my side?” [You think I don't know you curse me in your head every day?]
