1x21 - Aishiteruze Baby

Kokoro is mad at Kippei for not calling her even once over the summer like he has promised to do. Kokoro's friends tell Kippei that Kokoro is popular with the guys so he had better start acting like a real boyfriend or Kokoro would be swept off her feet by another man. Miki comes back for her things, now a happy girl, and watched Kokoro before she leaves to go home.
