かぐや様は告らせたい-ファーストキッスは終わらない- | show | 2023 | Official Trailer

The theatrical film that continues directly from Season 3 of Kaguya-sama: Love Is War, split into four episodes for streaming and home media. After years of romantic mind games, the two geniuses of Shuchiin Academy's student council — Kaguya Shinomiya and Miyuki Shirogane — finally shared a kiss at the culture festival. But neither of them actually confessed, and with no clear words spoken, their relationship remains completely undefined. Now painfully aware of each other's every move, the would-be couple faces the greatest battlefield of all: Christmas. Shirogane is determined to engineer the perfect first date, while Kaguya finds herself drawn to something imperfect and real. This is the very "normal" love story of two geniuses — and a first kiss that never ends.
