Little did Nao Kogure realize back in middle school that when she left an umbrella and a box of bandages in the rain for injured delinquent Taiga Onise that she would meet him again in high school. Nao wants nothing to do with the gruff and frightening Taiga, but he suddenly presents her with a huge bouquet of flowers and asks her to date him--with marriage in mind! Is Taiga really so scary, or is he a sweetheart in disguise?

Although Nao Kogure was once afraid of the delinquent Taiga Onise, she was soon touched by his kind soul. Nao and Taiga plan a romantic date on Christmas, but Yashiro, Misaki and Futami push their way in to make it a party at Taiga's house instead. Though their friends leave early to allow Nao and Taiga some time alone, someone else interrupts them--Taiga's mom!
