Uhm, some people seem to be missing the fact that Midori protected Doumyou.
Had Midori merely told Doumyou the truth, Doumyou would have pursued Tazune or been receptive when Tazune pursued her. But, for a moment, Doumyou experienced what it would be like to be with Tazune, and because of what Midori did immediately after that moment, the experience was made credible.
Midori was remarkably kind to Doumyou.
