Review Detail of Ginabut in Harry Potter and the Prince of Slytherin

Read up to chap 90 i had to drop becuz it became to boring for me. It was actually good, but the author kept changing his/her mind with the harem and author kept on saying he/she wont make MC op yet proceeds to kill 40+ mages with his OP PETS... was a 4/5 before the vampire arc now its just 2.8/5
