Will you... make love?

What happens when a brother and sister suddenly find themselves crossing lines they probably shouldn't is the entire premise of Nee, ...Shiyo♥, a 2-episode OVA from Studio 9 Maiami that leans fully into its taboo setup without much pretense. The story starts with playful, charged interactions between a brother and sister — the kind where you can already tell where things are heading — and then follows through on that tension without a lot of hand-wringing about it. The tone is intimate and unhurried, spending time on the emotional undercurrent between the two rather than just rushing through scenes. It's adapted from a manga, and that source material shows in how the character expressions and body language carry a lot of the storytelling weight. If you've watched something like Nee, Chanto Shiyou yo! and appreciated how that handled a similarly forbidden dynamic with some emotional texture, this scratches a comparable itch. Fans of titles like Love Me, My Knight who want something shorter and more focused might also find this worth the runtime. At only two episodes, it doesn't overstay its welcome — it sets up its premise, commits to it, and keeps the focus tight on the two leads. Going in knowing what it is makes the experience a lot smoother. It's not trying to be anything more than what it advertises, and within that lane, it delivers.
