HP: Space Ability at the Beginning, How Do I Lose?

Hp+Gryffindor+change regret+warm daily life Bai Hua traveled through time and came to the world of Harry Potter. While thinking about how to save his life, the golden finger arrived. So as a senior Harry Potter fan, he wanted to take a hard look at the scenery, and also wanted to change the people and things that made him regretful. Twin Weasleys: "You can trust Bai Hua when there is danger, but be careful of him when there is no danger." Harry: "Senior Bai Hua is really reliable. It would be better if you don't trick me." Hermione: "I really don't know how Senior Bai Hua's brain grew and why he can hold so many things? It would be better if he didn't bully my stupid boyfriend." Ron: "I'm really, woo woo." Harry said to Ron whose mouth was covered: "Stop talking, he's looking over!" Bai Hua turned to look at everyone and said grimly: "I see who is talking bad about me." (The protagonist is set to be 2 years older than Harry Potter, and enters school two years earlier. The protagonist is more serious at the beginning, but gradually reveals his fun-loving nature.)
