Shuchiin Academy's student council room – the place where Vice President Shinomiya Kaguya and Student Council President Shirogane Miyuki met. After a long battle in love, these two geniuses communicated their feelings and, at the Hoshin Festival, had their very first kiss. However, there was no clear confession. The relationship between these two, who assumed they would be a couple, remains ambiguous. Now, overly conscious of their feelings, they must face the biggest challenge yet – Christmas. It's Shirogane who wants it to be perfect versus Kaguya who pursues the imperfect situation. This is the very "normal" love story of two geniuses and the first kiss that never ends.
