藤原くんはだいたい正しい

Hitsuji Matsumoto, known as "Kigurumi-chan" for her mascot-like charm, is beloved by everyone at school—but she's frustrated that her popularity is more for her quirky persona than for being seen as a girl. When she realizes she's not treated as a romantic interest, the sharp-tongued student council president, Fujiwara-kun, delivers some tough advice: if she wants to be seen differently, she needs to act the part. Under Fujiwara's strict guidance, Hitsuji embarks on a mission to shed her "character" image and become someone boys might fall for. But as their dynamic unfolds, unexpected feelings and rivalries emerge. (Summary by Grok 2)
