The mailman's gondola is being repaired, so just for today, Akari is making the rounds with him to get the job done. As she learns the ins and outs of what it means to be a mail carrier, she meets a boy who needs his letter delivered at any cost. Whatever the envelope he's holding contains, it's very close to his heart.

A new vendor has opened up shop in Piazza San Marco, selling heart-shaped chocolates in glass bottles. Akari buys a bottle, and later goes to buy another, but by then, the patissier has mysteriously disappeared. Where did he go, and will he ever return?
