The beautiful Lok To (Michelle Monique Reis / Lee Kar-yan) mourns for her old love, Gala, who went off to Paris and has not gotten back in touch with her. One day, she finds a letter in her mailbox from Gala, stating that he has sent her 99 letters and that this will be the last one, as she has not bothered to reply. Her old penpal, Chanty (William So Wing-hong), moves into To's apartment building, along with his oddball Uncle Jet (Francis Ng Chun-yu), who discovers all of To's undelivered mail sitting inside his flat. A budding detective, Jet (a village chief who has relocated to the big city) comes up with a cunning plan to get To and Gala together. Having learned that the two used to work together in a bakery, Jet asks To to help him set up his own shop, reasoning that Gala (who will be returning to HK for his mother's funeral) will eventually drop by out of curiosity. The Seven Day Bakery is a success, with To's plain but specially crafted bread selling out everyday.Naturally, the more time Jet spends with To, the more he wishes that Gala (Conroy Chan Chi-chung, who looks and acts so much like Terence Yin Chi-wei, one wonders why the producers didn't just hire him instead) will never come back. However, return he does, and To is soon presented with an expensive ring. What Gala doesn't mention is that he already has a girlfriend, Ching-wai (Stephanie Che Yuen-yuen), and this leads to a tangled situation.
