As a little girl, Komomo Ninomiya delighted in picking on Natsu Azumi, the son of her family's pastry chef. Ten years later, when the family fortune is lost and she has no place to live, Komomo encounters Natsu again in her hour of need. Now that Natsu is a master pastry chef in his own right, he'll help Komomo-but only if she works for him at his new confiserie!

Komomo, in the throes of first love, doesn't understand the feelings she's having for Seto. She asks Natsu about feeling giddy, and he tells her that she's simply experiencing a head cold. But when Komomo finds out Seto's heart belongs to another, will Natsu be there to comfort her?
