Kono Kanojo wa Fiction desu.

A young man, infatuated with an older female classmate known for her writing talent, has neglected his long-held secret hobby for two months. For ten years, he meticulously documented a fictional girl's traits, conversations, and background in numerous notebooks, treating her as a close companion and lover. Deciding to let go of this fantasy, he attempts to burn the notebooks at a shrine. There, he unexpectedly encounters the older girl he admires. During a sudden downpour, she reveals her struggle with writing due to inexperience. Inspired by her honesty, he tries to share his secret, only to find that his bag now contains the fictional girl he created, physically manifest and nude.
