You have never been in love before

Well, maybe once before. But you learned the hard way that you got love sick. Like actaully love sick, whenever your heart would flutter you would have to run to the bathroom to throw up. But at least you could tell now if you were truly in love or not? But you weren't a very loving person. You were practically emotionless, so it was hard for you to fall in love. And absolutely no one knew about the whole "lovesick" thing. Like no one at all. Probably because no one as seen you fall in love. But today- you were doomed.

It was close to Halloween and your High School did an event to wearing your costume to school day. You wore your alien costume- but when you got to school you saw your best friend Kaidou. He came up to you with his usual excitement, jumping up and down as he showed off his vampire costume. Your expression was your usaul deadpan one but then your chest fluttered. You blinked then your eyes went wide- which was basically foreign from you and before Kaidou could notice you bolted to the bathroom, the door slamming behind you as you leaned over the toilet- gagging before puking into the toilet, hands gripping the seat so hard your knuckles were white.
