Sana opened the front door to find a man, in his 40's... (?)

   "Minatozaki Sana?" The man asked, speaking in fluent Korean.

   "Yes?"

   "You have a delivery from Chou Tzuyu." The man picked up a quite large box from the ground, handing it out to her.

   "If it's alright to ask, what do you do for the Chou's?" Sana asked.

   "I'm a personal butler for the Young Miss."

   "Ahhh.. Wait, I've already said there's no need for this." Sana exclaimed.

   "She has ordered me to give this to you as soon as possible." The butler tapped his foot, looking at his watch. "She also left you a note inside. It was nice meeting you, take care." Just like that, the man dashed off, leaving no trace of him for her to see in the dark. "What's the point of using night vision when I can't even track a butler?" Sana thought, chuckling a little.

   Young Miss? They're so formal... and busy.

   Sana entered the kitchen, taking the cover off of the large box sent from Tzuyu. Shrimp, Rice, Steak, Carrots, Strawberries, Watermelons, Grilled Cheese, etc. Way too many to name.

   An envelope laid at the bottom of the box, having those wealthy looking stickers sealing the paper inside. Nervousness built up as Sana tore the envelope, discovering a blood colored note.

   Dear Minatozaki Sana,
I hope you don't mind this. I've planned to ask the chefs to cook for you days ago as I'm going to be out with my family for the time being. If I suddenly act weird, I'm sorry. There's nothing to worry about. Fortunately, someone helped me write this, so it'd be easier for you to understand. Enjoy the food! And one last thing before our unexpected goodbye... I'll see you soon :x
                                                           With Love, Chou Tzuyu

   What did she mean about seeing her soon? Tzuyu also said it from the brief conversation with Sana earlier. Did she turn into a psychic? Was all of this planned from the start? Or will Tzuyu come home early? Questions after another, which one was the right answer?

   As Sana waits for the other members, her eyes concentrated on the paper. Re-reading it multiple times didn't help as it made her more confused.
"What are you doing?" Mina asked, placing her bag of supplies next to Sana's. Passing the note to the younger girl, Mina ended with a questionable look on her face.

   "What's this all about?" Mina bit her thumb, thinking of possible ways on what the note implied.

   "I honestly don't know. Tzuyu could be saying she'll come home earlier than expected, or..... She... knew this'll happen. ORRR we're overthinking this way too much."

   "How? It's not like we were doing anything unusual." Mina sits on the couch, finally realizing something that could be an answer to their question.

   "Our team! She'd know who we are, right? I love Tzuyu and all, but it's possible if you come from a wealthy family." Mina exclaimed.

   "We can't just assume that." Sana's voice shook.

   "Sana, her family owns A LOT of properties full of vampires. What are we? A group of killers. We're vampires killing OTHER vampires. Do you know how difficult it is coming in your own building and finding someone dead on the floor? Mina looked at Sana, who stared blankly at her.
"See? We don't even know how that feels." Mina scowled.

   "You're making it sound like we're murdering random people. Our job is to find criminals.
But if what you're saying is true, wouldn't our very first priority be THEM?" Sana asked with a bit of fright shown on her face. (A/N: I could've just said they're "vampire slayers or whatever you call it. To me, it seems cheesier than what I have now).

   "That's a good point. The Chou's would've been long gone if they took part of this, but there's way many more we killed, and they might be friends... O
