![Sekaiichi Hatsukoi OVA](https://u.livechart.me/anime/4620/poster_image/653243f5085beb5069542104fc468993.jpg/small.jpg)
Two OVA episodes featuring additional stories.
Episode 0: Ritsu and Takano used to date back in high school, but broke up due to a misunderstanding. This is that story.
Episode 12.5: Hatori and Chiaki go to visit the latter's family. It's really awkward in many, many ways.
