You woke up next to him. Again you had 'accidentally' slept with Armin. He was still asleep and probably didn't remember anything from your hook up. So, you quickly got up and left. What you didn't realise, was that you had taken his jacket rather than your own.

You were putting your books back into your locker when Armin walked over. His face was unusually happy, even for him.

"Is that my jacket?" Armin asked. Of course he would find out, it had his name written on the sleeves.
