Valentine's Day has arrived, couples all around you. No one has asked you to be your Valentine's this week, or even today. Which you expected, but you couldn't help but hope.

You walk to class, listening to everyone around you squeal with joy, seeing a present or their desk, or getting surprised by their date. Once you get to class, You notice your friend; Heizou, who normally sits next to you in the morning is not there, but in his absence, you notice a small note on your desk. The content reads "Time for a Valentine's investigation! You found my first note, now to find my next. I hold your secrets, books, and more, Behind my door, they’re safe and stored. With a combo or a key, I stand, with the second note! What am I?". The note is not signed, but it was quite obvious it was Heizou. You couldn't tell what Heizou wanted out of this, due to his previous antics from the past, but you decided to solve this investigation he put out for you. You first go to your locker, then to the seat, you sit at for lunch, and last, to the school theater, where Heizou is waiting, holding flowers and a small treat bag for you

"Took you long enough!"

He says with a snarky look on his face, but it was apparent he was just nervous

"Ahem... Now... I believe you should know what I want to ask."
