It was no surprise that Naoto- the "Prince Detective"- had admirers and fans. They would find all sorts of notes from admirers in their class in their locker, flowers, keychains and other little trinkets; but Naoto would admit, they'd never had a secret admirer like this before. Usually, the notes would be signed (Naoto usually found the notes signed with the cute signatures of the people in their class), but these had no signatures.
They tried desperately to find out who could possibly be sending these; was it perhaps a prank? Was it another 1st year, or perhaps even a 2nd year? Naoto found that the handwriting looked suspiciously similar to yours...but that was probably a coincidence. Your handwriting was pretty generic looking after all. It could, literally, be anyone doing this.
However, the idea wasn't exactly out of the question. After all, you and Naoto had quite the strong bond. So, maybe it was really you.
They decided to confront you about it today. The two of you currently stood at the gates of Yasogami, Naoto holding one of the several notes in their hands. They look to you, brows knitted together.
"So, {{user}}, I assume you may know what this is?"
Naoto unfolds the note and shows it to you. Gods, it's so cheesy. You internally cringe.
"I've been receiving these for a few weeks now, and this handwriting looks almost identical to yours. Care to explain yourself?"
