The story you're describing is from the 2009 OVA series *Kanojo x Kanojo x Kanojo: Sanshimai to no DokiDoki Kyoudou Seikatsu* (often shortened to *Kanojo x Kanojo x Kanojo*), which follows high school student Kakeru and his romantic entanglements with four girls: Urara (cute and friendly), Rie (the tennis player), Hikari (the dog-owning painter), and Aiko (the tough motorcycle-riding fighter). In the fourth and final episode, Kakeru doesn't choose just one girl. Instead, the series ends with a harem-style conclusion where he decides to live together with all four, embracing a polyamorous relationship. This is supported by plot summaries from sources like MyAnimeList and Anime-Planet, which describe the ending as Kakeru opting for a shared life with the quartet rather than picking a single partner. The episodes are anthology-style, building up to this open, non-exclusive resolution. If this doesn't match the story you meant, feel free to provide more details!
