I am going to assume that youre here because you have finished the anime yahari ore no seishun love come wa machigatteiru or OreGairu and want to watch the follow up OVA that takes place after the ending of the series. Ill cut to the chase and tell you DO NOT WATCH THIS The OVA is a horrible adaptation of the first 4 OreGairu Shin novels condensing 60000 words into a mere 20 minutes of animation. A lot of content is either completely cut or rushed and the OVA ends on effectively on a cliffhanger. This is very very bad but if you want to know more details then read the spoiler section of this review. If you are looking for the canon ending/epilogue of the series after volume 14 of the light novel or the final episode of the third season of the anime then go read the OreGairu Shin novels. Although Ill provide a couple addendums to its recommendation. The OreGairu Shin novels were included with the limited edition DVD/BD volumes of the Yahari Ore no Seishun Love Comedy wa Machigatteiru. Kan anime only released in Japan It does not have a legal western physical/digital release as of now The only translation Ive read were machine translated from a Chinese translation so its really difficult to parse and can be frustrating to read It does not have an anilist entry Since its not published as a standalone series but bundled with the Bluray it is a tokuten so ineligible to be listed I hope this was helpful
