Red panda Retsuko, worked to the bone, unleashes her frustration in the form of death metal. Lately, though, she's found another joy—getting the most likes possible on her Instagram posts. In fact, it is said that social media attention can release endorphins. As Christmas falls upon the city, Retsuko's hunger for validation only grows, pushing her to find new ways to embellish and sugarcoat her otherwise drab life for the internet to see.

Yasutake Shingo is a newspaper reporter whose only redeeming feature is his earnestness. He meets Matsunaga Chie, who attends a music college, and they start dating. Each day becomes all the more bright and enjoyable for Shingo because of the lively Chie. She loves to laugh, sing and eat. After one and a half years, Chie is employed as a music teacher. One day, Shingo is informed that Chie has breast cancer. After thinking about it, he decides to share a lifetime with her and proposes. His proposal gives her the courage to undergo surgery which she had been mulling over. One day, Chie starts to teach 5-year-old Hana the “important things in life” such as laundry, cleaning and cooking. She thinks that even if she is no longer around, her daughter and husband will be able to live.
