Side Effects of a Kiss: "He doesn't understand my feelings"

Miki is at her crazy house getting ready for school and her parents all left. Only her and Yuu remain in the house. She's been trying to avoid Yuu since ""the kiss."" But she can no longer avoid him and goes into the kitchen (where he is). This episode is where you get the name of the series 'Marmalade Boy!' Miki compares Yuu to marmalade saying he has bitter bits inside him but everyone sees his sweet looking outside: Marmalade Boy! And Yuu compared Miki to mustard: always sour and spicey, Mustard Girl! Well, Miki's strange family seems to get along together (though it is rather strange...).
