He has autism and is trapped in his own silent world, unable to break free. But one day, she accidentally enters his world, and from then on, his world becomes her.
She is an unwanted child, living under someone else's roof. Then he gets clingy, gradually taking over her world, and everything begins to change.
Dark and ruthless become his defining traits. He will stop at nothing to get what he wants, sinking deeper and deeper along the way.
P.S.
1. This is a story about a man pursuing his wife. The male lead gets tortured, not the female lead. A little angst is fun; too much is bad for your health.
2. The male lead loves the heroine without limits. By "without limits," I mean in terms of his character.
3. This story is purely for my own amusement. If it's not your thing, enter with caution.
It's very well written. Why don't you update it?
