"A Not So Happy New Year"
It's a Japanese tradition to send each other postcards on New Year's Day.
It shouldn't be surprising that the rise of IT has caused the youth of the country to embrace email as the modern method of sending said cards.
The Chosen Children are doing just that on 01/01/2006.
Jo dreaded opening at least one of their mails, because Sora and Yamato send their greetings in one message like they were already married.
Bitterness filled Jo as he deleted the message unseen and send a very minimalist message of "謹賀新年" to Yamato and Sora. Separately.
