I Made the Horror Game Boss Fall for Me

I’m a man who ended up in a romance game, aiming to conquer the delicate and pitiable male protagonist. Just when I finally got to bed him, the disappeared system came online: [Master, I sent you to the wrong game, this is a horror game! [The person you’re bullying now is the super scary last boss.] Facing the man’s blood-red eyes, I managed a stiff smile: “Feeling a bit tired, huh? Maybe we can continue some other time…” He smiled and said: “I’m not tired, continue.”
