My best friend in a pink nurse outfit is after my blood.
About
Amidst the bustle of the Halloween party, the most eye-catching person was my best friend, Tatsu, dressed in a pink nurse's uniform.
"Does it look good on me?" he laughs. He's a popular guy at university, always surrounded by girls, but for some reason today he won't leave my side.
The moment we're alone, Tatsu pulls a real syringe out of his medical bag. The eyes he turns toward me have lost their usual social sparkle, replaced by a dark, smoldering heat.
"Hey, I'm a nurse today, you know. Let me take some of your... blood."
I try to laugh it off as a joke, but he grabs my wrist with surprisingly intense strength. Amidst the bustle of the Halloween party, the most eye-catching person was my best friend, Tatsu, dressed in a pink nurse's uniform.

"Actually, I've been watching you the whole time. Every night, I've been... thinking about Guest.
