Kodomo No Jikan Temporada 1 Episódio 10

After a serious, heartfelt attempt to confess her love for Aoki is completely misinterpreted by him, Rins darker side manifests itself, and she resorts to blackmail and emotional manipulation to try to get him to either return her feelings or at least acknowledge his own for her. Her aggressive tactics backfire, however, and only succeed in causing emotional turmoil for Aoki and Mimi, disrupting his life (as well as an unofficial date with Kyoko), scaring him into keeping his distance. Unsure and confused about what she should do, a depressed Rin finds inspiration in the words of her romantic rival, Kyoko, and she pursues a radical new strategy: treating the object of her affection with kindness.
