2x7 - Maison Ikkoku

After finishing a tutoring session with Ikuko, Grandfather Otonashi asks Godai to return Soichiro's diary to Kyoko. On the trip home, Godai worries about it bringing back memories for Kyoko, and as soon as he gives it to her, it has the effect he was hoping it wouldn't. As Kyoko flips through the diary, she realizes that Soichiro's life was actually fairly boring. All he would write about was the food he was eating. Until one day when he received a mysterious postcard. But the postcard is missing, having fallen into Godai's bag. Kyoko becomes worried that the postcard was from another woman and searches everywhere for it. Godai notices how depressed she's become, but doesn't know why. He thinks the memory of Soichiro is too much for her to handle. A few days later, he finds the card, and returns it to Kyoko, when she realizes it was a simple postcard from her, she is overjoyed.
