Maaya Kisaragi, 16 years old, finally confessed to her crush…only to be flatly rejected and ridiculed on social media after. To make matters worse, the most popular guy in her grade, Chigira-kun, overheard her despondent muttering about the whole thing. But instead of making fun of her, he comforts her…and proposes an odd solution to her heartbreak!
“It’s a symbol that I’m Chigira-kun’s girlfriend.” Maaya promised to be by Chigira-kun’s side forever after receiving a ring from him on her birthday, which they spent alone together. Because she’s always receiving happiness from Chigira-kun, Maaya is worried about how to return the same happiness to him. So, she comes up with the idea of inviting Tezuka-kun to the Christmas party being held at the Chigira home. This is a Christmas story that continues late into the night!!
