It couldn't be, it just couldn't be her, it couldn't be Amy, it not her!

Sonic keep repeated it in his head over and over and over again. He didn't want to believe it, couldn't believe his own eyes what happened behind that door.

He should had know, should had detected it sooner from the ways she acted lately, should had realized she recently avoided the group, avoided him.

It happened on the first April. The official day he and Sally became a couple. They had been childhood friend since at young ages. He liked her and she liked him, simple! His friends congrats them that he finally grow a ball and confess his feeling to Sally. Of course, he knew this action will break her heart in pieces. But what can he do? He only loves her like a lil' sister, he didn't love her in that way. Why couldn't she understand?

Even so, she still joined the group at lunch, smiling, chatting with them like nothing happened but she wouldn't look at him, not even once. He didn't bother because he knew she would get over that it and moved on.

And oh! How wrong yet right he was.

It happened during the Valentine day and the continuity day after.

Normally, Amy would go with Cream on the way home. But after the V-day, Amy constantly stayed after school to finish her 'subject' with the new teacher. Sonic didn't know much about this teacher, just knew he is that Mister-Grumpy-Face brother. And that not a good sign. Definitely really bad since Amy didn't know anyone in her class. Classmate – yes, friends? No. She should make some friends in there but since the day he dated Sally. She requested to be moved other class, away from her friends, away from him.

Knowing Amy had to stay after school. Cream did say she could wait for her but she declined, saying she didn't have to. So, during the after school, Cream will walk home with Tails instead.

Of course, when Amy said she has to stay after school because 'subject', he believes her. But, it was getting ridiculous, she always stays behind after school and it started to get on his nerves. He afraid she might be bullied or something, but with a hot head like Amy? It's hard to believe.

Maybe he didn't accept her love to him. She's still his friend and he cares deeply for her safety. Even he only loves her as a sister

So, he began investigate, no more running from her again.

And he instantly regretted.

The sound of skin slapping over and over kept ringing in his ears, making him cringed. Clapping his ears from the sound and shutting his eyes tight, he didn't want to believe it was her, inside that room, doing it with… Him!

It was unbearable thought and it making him sick. Why? He thought to himself.

Why Amy? Why him? He is your teacher for Chaos's sake! Why would you even want him!?

Now he knew why she always stays after school, why she looked so pale recently, why she so tired easily, sometimes jubilant even on the harsh day, knew why she didn't bother to look at him longer, knew why she always gets… good grades.

"Ah ah ah ah! P-please…"

Please? Wait, maybe, it's not what he thinks! Maybe, it was a mistake and-

"Harder… Ah! Huff huff… Keep going… Hah hah… Don't… Stop… OH!"

That was it, he couldn't take it anymore.

He ran as fast as he could, knowing his own speed, it was easy for him to take a second to the gate school. But he didn't stop there, no.

He kept running, running from what he heard, running from the thought, running from her.

Now he knows the truth, what is he going to do?
