[Harry Potter] This Potter Comes from Slytherin

Set during third year.

The premise is that Snake Harry transmigrates and turns dark after losing his partner.

He can't help doing all sorts of things to little Draco~

P.S.:

1. Harry refers to the Harry in this world, while Harry refers to Snake Harry.

2. This is a self-indulgent work. Apologies if anyone is out of character.

Theme: All the love, hatred, and obsession ultimately form a closed loop.
