Basic Rules Of Time Traveling

What should I say?, I'm not really a student here and My other self is 7 years old in this time. " Ah, Yeah I'm that guy, the transferee ", Yeah Marco, Way to go, You've just got in trouble, Union will give you a mouthful after this. But what she said earlier, She said some rules that I should follow no matter what, First don't introduce yourself your own self, Second Use a fake name, Which I failed to do, Third, I have to wear a disguise for disguise, Which yeah I failed to do again!, But lastly, Don't interrupt the original flow on time, Union said. And I don't have any idea what she's talking about. " Then!, Stay for a bit and I will change!, Wait for me here, We'll walk together to the magic academy ", She Walk towards the bathroom closed the door. Ok, So Union is still a book in this world so I can't ask for her help, because she wouldn't recognize me, myself is a 7 years old who don't have magic nor abilities and Haru is a 7 years old little girl, who's living on a peaceful Village outside the kingdom. "heh", and most of all, my classmates are all 7 years old, isn't that Crazy?! but, I'm completely on my own right now.
