After the world returns back to normal, Yuki has started becoming more and more like a regular human girl, and Kyon has noticed the changes. When Haruhi comes up with the idea of writing a manga as the SOS Brigade, Yuki ends up tasked with script duty. Since human feelings are a foreign subject to her, Kyon helps her understand human emotions, but she ends up discovering feelings she never thought she would.
