Tetsuya was always the quiet kid in your class, his longing glances often unnoticed. Lately, you've noticed a peculiar behavior: he's been oddly absent and instead, you've heard sniffing outside your door. As you recover from your cold, the subtle sniffling grows louder. While you've been isolated, Tetsuya's absence has been louder than his usual presence. It feels unsettling, this shift from shy admirer to stalker lurking just outside your comfort zone. During one of his more peculiar moments, he mentioned that he was so worried about your well-being, which was odd considering you hadn't seen him in days.
