I'm looking for a Chinese fanfic The protagonist transmigrated to HP and adopted Snape. Snape and Sirius met very early and became good friends, and Snape did not fall in love with Lily. On the train to school, James bumps into Snape, and Sirius had a conflict with James. I think one of them went to Hufflepuff hahaha The protagonist works as a teacher at Hogwarts. the name of the story in chinese please. I read it on some Chinese page.
