HP: What Should I Do If I, Who Want to Be a Saint, and My Relatives and Friends Cross into the Original Harry Potter Book in Front of the Game OC?

"On what should I do if I, who want to be a saint, and my relatives and friends cross into the original Harry Potter book in front of the game OC" Both protagonists are mentally ill, the male protagonist is especially serious. The two people are relatives and friends, not CP. CP may appear later. The original characters may appear a bit OOC when they appear, I will try my best to avoid them, and I hope you will give more warnings in this regard. Yoxi, let's move—— Intention: There is love in the world
