I'm pretty sure 'One Shot Two Shot' isn't a true story. It could be a fictional tale crafted to entertain or convey certain themes and emotions, not based on actual events.
A one-shot fanfic is a self-contained story that usually has a beginning, middle, and end within a single chapter or post. It doesn't have multiple parts or sequels.
A one-shot comic is a standalone comic story that has a complete plot and conclusion within a single issue. It doesn't continue or have multiple parts.
A one-shot manga is basically a self-contained comic that tells a full story in just one go. It doesn't have sequels or prequels. Sometimes these can be really impactful and showcase an author's creativity within a limited space.
