Ai Yori Aoshi

Star Festival (1x13)

:

Tanabata is more than just hanging written wishes on a wreath at the Sakuraba Mansion: It also happens to be Aoi's birthday! After suggesting that they throw a big bash, Kaoru starts working extra hours to buy Aoi an outfit he sees on display at a clothing store. But since this gives him little time for leisure, the birthday girl almost believes he doesn't care about her anymore. And just when it seems Kaoru's hard work has gone to waste, both he and Aoi are in for a pleasant surprise.
