Seito Kaichou desu ga Josou Hajimemashita

Jun Shiraishi has long harbored a quiet yet earnest desire to experience the genuine companionship of a close female friend. This heartfelt longing comes to the surface when she bluntly rejects a young man attempting to court her, choosing instead to confide in him about her unfulfilled wish. Moved by his strong feelings for Jun and determined to win her over, the persistent suitor takes a remarkably bold and unexpected approach. He decides to cross-dress as a girl, successfully infiltrating her life and forging a close friendship with her under the alias "Nai." This sets off an intricate and unusual dynamic as he navigates the delicate line between his true identity and his disguised persona, all while trying to bridge the gap in Jun's social life from an entirely unprecedented perspective.
