The unexpected reunion of us

Hello, again?

It was a friday afternoon, at Central Bay High School, i was walking in the hallways, heading to class with my friends. When we walked in i noticed how there was a substitute. I sat down and waited for the substitute to say my name during the attendance.
"Lilian Martinez"
"Here!"
After attendance was done, a few minutes have passed by of doing nothing in class, i realized i was kinda of thirsty, So i opened the door and headed out. After i had finished drinking from the water fountain i slowly walked back to class. As i was about to enter and open the door, i realized somebody was already opening the door. When the door finally opened, i saw him.

He had a sharp jawline, unlike me who had a soft side profile. A tan-ish colored skin that contrasted with my colored skin. Green colored eyes that were combined with the color of sky blue. And lastly wavy hair that used to be curly hair, back then when we dated.

After i have had bumped into him, we stood still for a couple of minutes, but those minutes felt very long. I was hoping for these minutes to be over by now.

"So are you gonna move?" Asked Andrew
"Huh?" I said after i realized i kinda zoned out on him. 
As i was about to move and go back to class, i heard Andrew's voice
"Stop" said Andrew
"Listen we need to talk, i heard from others saying, you wanted to talk to me".

From these sudden words, i felt confused. Who told him, that i needed to talk to him?

"I dont know where you heard this from or who told you this? But ever since we broke up, i stopped associating us together".
"Are you sure? Lilian" asked Andrew
"Yes i am sure" i said feeling awkward yet so much tension between us.
"But if what you're telling me was true, shouldn't i have to be the one to come to you instead of you coming to me".
"Yeah you're right and by the way dont think i am trying to be your friend but i know theres something you been wanting to tell me".

I thought to myself, Is he trying to say that we can only talk if we're friends? I didn't quite know what he meant by "not trying to be your friend". But honestly i didn't care and i knew he didn't either.

"Whats the point in asking me, what i need to tell you, when i know that in the end your gonna end up not caring". I replied
"You're right, ever since we broke up i stopped caring about you but i have curiosity".
Damn. "I stopped caring about you" i did too but the way he said it, is harsh. But If he truly stopped caring, why is he talking to me right now?
"Are you hearing yourself Andrew? your saying that you don't care and that i have something to say to you but your the one who came up to me and you keep trying to make me tell you something, i think your high."

When we used to date, he used to get high a lot but now that i realize this whole time we been making eye contact and talking, his eyes were red.

"Yeah thats why i needed to leave class, so i can go to the bathroom but you just happened to be right there Lilian". He answers
I had enough of this and i just wanted to go to class, but honestly i didn't mind me and him talking, it actually felt nice and not awkward. I decided i would tell him what i truly wanted to say to him and afterwards i would leave.

"Just tell me Lilian, theres a possibility i wont even remember what you told me, tomorrow".
"Well then Andrew, i want to be on good terms, it seems like we hate each other ever since we broke up".
"I dont hate you, i just simply stopped caring about you".
"So then are we cool". I asked
"If thats what you want, then yes we're cool".

There was a long pause, there was an awkward silence, but yet i felt so much tension at the same time.

"Alright Lilian, i think its time for you to go back to class".

Thats what i wanted to do, there was no point in having the conversation go on for this long. But there was something that was stopping me, i didn't wanna leave yet.
This caused us to just stare at each other for a long period of time, i realized that he suddenly got closer and closer to me.

"What are you thinking about Lilian, is there something that you wanna do?"
"No" i said feeling flustered, i didn't expect him to break the silence.
"Well then i think you should get going".
"So you're just gonna make me leave? I thought you would do something else".
"Well what did u expect me to do". He asked.

It got to the point, where i got close to him, Andrew had an expression of confusion but he stood still, I knew he wouldn't have expected me to do that and i didn't either.  We were so close to the point that our lips were touching but none of us actually took control of the situation to do something. Suddenly, I heard the sound of the door opening, I quickly moved away from Andrew and saw the substitute yelling at both of us to go back to class.
