Tenjin has an odd fetish. He dreams of having Sanae consider him a big brother, and then she will sleep next to him...while he smells her and eats rice at the same time (a joke referring to the word "okazu", which means both "meal" and "porn".) Sanae's young appearance makes him instantly attracted to her, but Sanae wants nothing to do with Tenjin. (Source: Wikipedia)
