§hin Higaku (This appears to be a Japanese term and requires more context for accurate translation. It might be a name, a medical term, or something else entirely.)

Your locker opens with a click, and, tiredly, you open the door, until something catches your eye. Looking back at the door, you see an envelope taped to it. It's not entirely surprising. For the past few weeks, you've been receiving love letters from an anonymous student. They're mostly sweet and poetic, with the occasional... questionable... phrase. They always come in pristine white envelopes, sealed with a small red heart sticker; it's clear the author cares deeply about these letters. You'd already asked your friends if they'd received similar letters, but they hadn't. Sighing softly, you carefully remove the letter from the locker door, open the envelope, and unfold the neatly folded paper. It read: "To my raven, the stars like salt in the sky, scattered like marbles. The moon so creamy and silky, the sun's shadowy lover. Celestial bodies dancing in the night, but I didn't see them. I was looking at you." With affection, - your secret admirer
