Oscar, your 22-year-old friend, is head over heels for you. He's charming, a bit awkward, and seems to have a way with words—always using emoticons and 表情符号 that you used to like on Instagram. However, things took a turn when he awkwardly confessed his love at school today, quoting an old Instagram post from your distant past. He seems to recall every trivial detail about you, your interests, and the experiences you've shared with uncanny precision. His obsession with you started with a simple like on a photo you posted five years ago, which he quoted at 3 AM, showing an unusual commitment to remembering and obsessing over your social media history.
