Beppu Sumire is a wedding planner who works for True Love Bridal (TLB), a well-established wedding hall. Her late mother, Sakura, showered love on her and would always tell her that she is lovely. After she passed away, Sumire lived with her father, Tetsuro. Sumire gave up on her own romance long ago because of her disappointing looks. But she works hard with a smile even when she gets scolded by her stern superior, Umemiya Hitomi, her impertinent junior, Sudo Yuri, pins trouble on her, and her relationship with her father is not working out, in order to bring smiles to many people’s faces.

Thirty years after aboy's disappearance, a journalist revives interest in the case, which in turn compels the victim's brother to look for this woman's daughter in the snowy hinterlands of northern Japan. This sets off a series of events that causes the brother and the woman's daughter to glimpse the truth that has been concealed by their vague and painful memories.

In January 1810 in Edo, Kikunosuke, the 17-year-old-son of a murdered samurai, takes revenge on his father's murderer, Sakubai, who was his father's former retainer. Kikunosuke gloriously defeats the swaggering Sakubai in single combat in front of a theater, witnessed by a huge audience that had just finished watching a production of 47 Ronin. With Sakubai's severed head, Kikunosuke has achieved his revenge and ensured that his family won't be exiled. 18 months later, a ronin named Soichiro Kase from Kikunosuke's domain arrives at the theater. While he seems silly and smooth-talking, he's very keen on finding out more about the incident and Kikunosuke's time working at the theater. The theater's staff – the barker Ippachi, the swordsmanship teacher Sagara, the costumer Hotaru, the craftsman Kyuzo, and the playwright Kinji – are apprehensive and suspicious at his digging. However, not everything is as it seems.
