HP: Wormwood and Lightning Wood

Two male leads! Two male leads! Two male leads!
The main character is an original character, and the main couple is Snape.
Main pairing: West Porter x Severus Snape
Side pairing: Harry Potter x Draco Malfoy
There are some personal settings! A satisfying read! No painful moments (maybe...)! The main trio won't break up, nor will Ronnie and Harry; the protagonist dotes on Harry.
Twin brothers West Potter and Harry Potter enrolled at Hogwarts together, one sorted into Slytherin and the other into Gryphon.
Because of his striking resemblance to his mother (not a substitute story!), West gained some attention from the Potions professor, and he wanted to monopolize that attention to protect the person he loved.
✨Extreme protection and extreme favoritism
