IV

Y/N's POV

6:36 AM. And not a wink of sleep. I couldn't get off my mind that Mai Sakurajima kissed me. Truly, I'm grateful and jumping for joy. I'll just have to see how it goes. I look at her in a peaceful state of sleep. I move some of her hair out of her face. However, Mai seemed to move from my touch. 

"Good morning." She says, wide fully wide open. "Sleep well?" 

"No. Not a wink. I guess taking that energy drink was a bad idea. Or a good one. I don't know..." I replied. 

"Silly, what did you expect? We should get ready since we still have school. I'll go ahead and change." She gets up from the bed and I do the same to give her space. I head to the bathroom first and wait for her to finish.

We arrived at school fairly quickly. So far, seemed like everything was normal, except the fact that we had midterms coming up. I could only mutter in frustration. Regardless, that's not the important problem. The real problem is: it seems like, everyone at school...

Forgot about Mai. 

Some people have even almost bumped into her thus I have to move her out of the way gently. It's still hard to tell since most people didn't pay any attention to her in the first place. I try to remain positive, even asking some people if they know who Mai Sakurajima is. 

"I'll check my class," Mai said. I nod and watch her walk up the stairs.

"Y/N." Futuba comes to my side, pulling my sleeve. "I have bad news." She said. 

"I know. I can see it as well. Everyone's forgotten about her except us." 

"Even Kunimi and Sakuta." My eyes widened at the news. 

"You're kidding? Right?" She shakes her. I only sigh and look over at her. "Any ideas?" She nods. 

"I do, let's go." I follow Futuba to her lab. We both enter and sit down across from each other. Rio makes a coffee while I stare out the window. 

"So, any ideas?" I ask. While she stirring her coffee, she looks over at me. 

"I have a possible idea. First off, did you get any sleep last night?" She asked. I had a bad feeling about this.

"I didn't. But, to be fair, I had an energy drink." I said. "If I didn't take it, I would've knocked out," I replied in a joking manner. 

"I believe that's the problem. I didn't sleep either. Because we didn't sleep, we remember her just fine as a normal person. Do you remember the theory I told you about?" I nod. 

"Yeah, Schrödinger's cat. The observation theory."

"Correct. And I also mentioned another thing to you as well, that the key to this problem is in this school. My theory is, the entire school IS Schrödinger's box. Notice even before, everyone treated her like she was invisible. By going with the rules of the Observation theory, since no one is observing Mai, her existence deteriorates over time, making her fully disappear. Thus, meaning another thing," She says. "And I think you know yourself." I fully try to grasp this information before my eyes quickly widen at what Futuba's hypothesis is.

"As soon as a person sleeps, they forget meaning... that energy drink, is the reason why I'm able to see her now, because if I didn't take it..."

I would've forgotten about her. For good.

I can't help but have a troubled expression on my face. Mai pointed it out earlier, asking if I was okay. Of course, I lied and replied I was fine. It looks like I have to focus up here and purchase some energy drinks. Thus, I went over to the store and purchased a couple of energy drinks and pills to keep me up for the next few days. I head to my apartment and make my way to my room. However, Sakuta spots me with a massive bag.
