Qualification of Love: "You don't deserve Yuu"

It starts with Meiko writing in the diary. Thinking what she said that day and telling Miki that she thinks it's courageous of her to think of him instead of herself. The next morning Miki's in bed thinking about the almost kiss with; Ginta and then having Yuu break it up. Not knowing how to face them. That day at school during class Meiko starts daydreaming about her last date with Shinichi and what they promised each other. Satoshi goes to the library hoping to find, Meiko. He sees Yuu instead and then saying something that creped him out. Miki, running late for practice sees Arimi on the way and gets and apology for the scheme. Then explaining tings to Miki she runs away. Meiko's parents on the other hand; have another fight. How does this affect Meiko?
