"Him again" is about a girl named "Kim Seo Yeon" (you) who is in her secound year of high school in "Seoul High School" and has many friends but her closest friend is "Min Seo Shik". But the thing is that the one boy who she always liked  in middle school was going to be in the same school her again. His name was "Shik Gong Chan". It was the worst thing ever for you because your sister "Kim Tae yeon" knew you liked him so of course like the dork her sister is she has to for it. But trust me that is not the wost thing about this high school year........The wrost thing is........Gongchan  happens to be Min-seo's brother?!
