The protagonist is visiting a shrine together with a girl named Mochizuki, and he can't help but praise the kimonos worn by other girls... yet the one he actually wants to compliment is hers. That puts Mochizuki-san in the mood to roast some mochi. Note: The title mochi wo yaku (もちを焼く) "to roast mochi" is a play on words that sounds like the phrase yakimochi wo yaku (焼もちを焼く) which means "to be jealous".
