I really and truly enjoyed this prequel Ova. It was really good and i thought it was very sweet, touching, and totally fits what had happened before the start of the series. Rumiko really knows how to make good plots.
The story focuses on what happened before Kyoko works at Maison Ikkoku and what her life was like before she met and married Soichiro. It also explains who Soichiro was (as a person), why Kyoko loves him so much, how Soichiro the dog came to live with Kyoko and them, events of Soichiro's death and funeral, and why Kyoko had decided to become a manager at Maison Ikkoku and how the whole series began.
It's a really good prequel and it's focused on Kyoko's point of view and how she describes how life was life for her back then and stuff. You'll even see glimpse of the main characters (in cluding Godai) and some clips of Soichiro's face.
It's a really good prequel and if you seen the anime or read the manga and have completed it and wanted to know who Soichiro was and what Kyoko was like back then, watch this prequel Ova. You'll really love it and it will have you really feel and understand exactly Kyoko's emotions and feelings through this Ova. It's worth it!
