Kaguya-sama wa Kokurasetai: Otona e no Kaidan

Years after graduation, Kaguya Shinomiya finds an old photo album that pulls her back to her days on the Shuuchiin student council. At that time, she had finally begun dating Miyuki Shirogane after a long war of pride, schemes, and delayed confessions.

Her memories return as a series of sweet and ridiculous moments from the awkward beginning of their relationship, when the two were learning how to be a couple without losing their competitive instincts. Looking back now, Kaguya can see how those clumsy first steps quietly led her toward the life she has grown into.
