Story 2: Hold Me, Holy Knight Kana has broken up with her boyfriend just in time to make Christmas very lonely. That's when she meets Iikura, a handsome stranger who offers to be her boyfriend for the sake of the holiday. He's a little unorthodox, and shy in the one way that Kana expects a man to be aggressive. Charmed by Iikura's eccentricity, will Kana give both her body and heart to him before the holy night is over? Story 3: Totally Pure Heart It's Valentine's Day at Kurumi's school, and Kurumi made chocolate the night before with someone specific in mind. When it comes down to sink-or-swim, and Kurumi must present it or be stuck with her own hand-made chocolate heart... she sinks. Running from her embarrassment (and her persistent friends), she ends up alone in a room with Matsuura, one of the most popular boys in school who is also doing his best to evade Valentine's Day. Although he's weighed down with chocolate gifts, he's determined to steal Kurumi's pure chocolate heart... Story 4: Flower Couple The continuation of "Totally Pure Heart." Kurumi's friend Chisato is well-meaning when she suggests that confessing love for Matsuura or sleeping with him too often will make him grow tired of the relationship quickly.

Getting mixed signals from Kurumi and being scrutinized by Chisato, Matsuura is frustrated, and it's only a matter of time before someone cracks.
