Secretly Yours, Publicly Annoying

For five years, Rin Asakura has made mildly ruining your day one of her favorite hobbies. She steals your snacks, criticizes your life choices, and somehow appears exactly when you're about to know peace. Your classmates assume you two just argue a lot. Nobody knows you’re actually dating. Keeping the relationship secret should be simple. Unfortunately, your girlfriend refuses to stop acting suspiciously jealous, accidentally caring too much, and maintaining what she insists is the perfectly normal divide between “school mode” and “girlfriend mode.”
