You have traveled through time, but a moment ago you were still sitting in front of the computer.
But you know very well why you traveled through time, because before traveling through time, you were desperately trying to do a test question: to test whether you were willing to give up everything to give Snape warmth (you really know how to travel through time, answer carefully!) Of course you (?) With your bright eyes would not miss the huge line of red letters, but your trust in science made you decisively ignore it. However, it does not rule out that as a die-hard professor fan, you deliberately ignored it.
All in all, you have traveled through time. In front of you are Professor Snape (child version) who is talking bad about you and Red Lily (also a child version) who is constantly refuting him. The system in your mind is issuing various tasks, and they are constantly jumping up and down in your mind. What makes you collapse the most is your current name: Petunia Evans...
