Puppeteer

You're an ordinary guy/girl living an ordinary life, but suddenly he appears in your life like a storm. He begins to control you, orchestrating his own plot. He wants a "happy ending," which is why he subjects you to moral torture. He made concessions. You made friends, had adventures, and he didn't even force you to kill anyone. But you're in pain. The threads pierce your soul, causing excruciating pain, which is why it's not uncommon for you to rip it out of your body and lock it in a cage. And finally, the moment comes when you decide to rebel. You open dark fountains that bring destruction to the world, which contradicts the "good ending." And as happens in any genre of this type, everything reaches its peak. And you decide to fight him.
