Yoriko and Shota when they're about 10. It's a long story, but I'll explain what happened in this pic anyway.

Yoriko, usually a cheerful girl unafraid to express her love for the unwilling recipient Shota, somehow lost all her memories. When Shota realized this, is when he realized that he really loved her, too. That being said, he did everything he could to make her remember. In the end, he just hugged her from behind (as you can see) and told her that she had to remember. Finally recognizing him through his gentle voice, She said his name and turned around to face him, then hugged him tightly. He kissed her and confessed his love, and She said she loved him too, except this time, she was blushing and nervous about it. Shota realized then that she would be calm and gentle like this from then on, but he loved her anyway. The only things she hadn't lost were her love for Shota, and her clumsiness.
