Stupid Childhood Promises in Anime, and Three Days of Happiness

Do you remember in specific detail, your best friends in elementary school? Do you remember the stupid throwaway promises you made as a kid? Are your experiences with your elementary school friends the ones you remember most and hold most close to your heart? Are you still in love with your crush from years and years ago in elementary school? If you’re the protagonist of a shitty anime/manga/visual novel, then the answer to this is most likely yes.
