Jun, a shy, introverted, and self-conscious boy, navigates the tumultuous waters of high school romance. He's hopelessly smitten with Yuki, the school's popular and seemingly unattainable queen bee. While Yuki, despite her tough exterior, harbors a secret crush on Jun, her attempts to express her feelings are met with his crippling lack of self-confidence.
 
As Jun struggles to believe Yuki's genuine interest, he's bombarded by the affections of other girls, each with their own unique and often bizarre approaches. From the bubbly and optimistic Hana to the obsessive and slightly unhinged Aiko, who literally pours her blood into homemade chocolate for Jun, the journey to love becomes a hilarious and heartwarming rollercoaster ride.
